To solve equations, you isolate the variable you are solving for on one side and everything else on the other side.

The first step to solving this equation is to combine like terms.
Combining like terms means to add up all terms that have the same variable(s) and exponent.

If no exponent is shown, then a 1 exponent is implied. The reason why we don't show a term raised to the first power is that it doesn't have any effect on the term.

I see three terms with the x variables. We can combine them. Why? Because they all have the same variable and exponent.

I'll rearrange the left-hand side to combine all the terms with the x variable.

Now we have -3 + 2x - 4x - 2x = -6
Combine all terms that have the x variable.

-3 + 2x - 4x - 2x = -6
-3 - 4x = -6

Now we have -3 - 4x = -6
What can we do now to isolate the x variable on the left-hand side?
For starters, we can add 3 to each side of the equation.
That way the -3 term will disappear.

-3 - 4x + 3 = -6 + 3
-4x = -3

Last step.
The x variable is being multiplied by the -4. If we reverse that operation
we can get the value of x.

-4x / -4 = 3 / -4
x = 3/-4 or x = -0.75

Answer:

Step 1 :Combine like term to perform the operation .

Step-by-step explanation:

Given  : 2x – 3 – 4x − 2x = –6.

To find : what should be your first step in solving the given equation.

Solution : We have given 2x – 3 – 4x − 2x = –6.

Step 1 :Combine like term to perform the operation .

2x - 4x - 2x -3 = -6.

-4x - 3 = -6 .

Step 2: On adding both sides by 3

- 4x = - 6 + 3 .

- 4x = -3 .

Step 3 : On dividing both sides by -4.

x = 3/4.

Therefore, Step 1 :Combine like term to perform the operation .

Answer: Choice A) There must be a vertical asymptote at x = c

Explanation:

The first limit \displaystyle \lim_{x\to c^{-}}h(x) = -\infty says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.

The limit \displaystyle \lim_{x\to c^{+}}h(x) = \infty means that as x approaches c from the right side, the y values head off to positive infinity.

Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.

I need help with a math question that is 0.1x = 5/y
BabaBlast [244]
Unfortunately you have not included the directions.  Are you supposed to solve for x?  or for y?

Suppose the directions say, "Solve for x."  Then, clear out the decimal fraction by mult. both sides of the given equation by 10.  This will give you the solution, that is, a formula for x in terms of y.

So.. take a peek at the picture... let's get two points from it, hmm say 0,4 notice it touches the y-axis there, and say hmmm -4, 1, almost at the bottom of the line

\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ 0}}\quad ,&{{ 4}})\quad 
%   (c,d)
&({{ -4}}\quad ,&{{ 1}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{1-4}{-4-0}

\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\textit{plug in the values for }
\begin{cases}
y_1=4\\
x_1=0\\
m=\boxed{?}
\end{cases}\\
\textit{and solve for "y"}
\end{array}\\
\left. \qquad   \right. \uparrow\\
\textit{point-slope form}

once you get the slope and solve for "y", that'd be the equation of the line.
