−2+2x=−2+7
Step 1: Simplify both sides of the equation.
−2+2x=−2+7
2x−2=(−2+7)(Combine Like Terms)
2x−2=5
2x−2=5
Step 2: Add 2 to both sides.
2x−2+2=5+2
2x=7
Step 3: Divide both sides by 2.
2x
2
=

-2 + 2x =x + 2 + 7

First combine like terms
-2+2x=x+9

Then get the variable x on to one side
-2+2x=x+9
-x -x
----------------
-2+x=9

Then get x by its self
-2+x=9
+2 +2
------------
x=11

Choose the equation that represents a line that passes through points -3,2 and 2,1

STatiana [176]

bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-2}{2-(-3)}\implies \cfrac{1-2}{2+3}\implies -\cfrac{1}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-2=-\cfrac{1}{5}[x-(-3)]\implies y-2=-\cfrac{1}{5}(x+3)$

$\bf y-2=-\cfrac{1}{5}x-\cfrac{3}{5}\implies y=-\cfrac{1}{5}x-\cfrac{3}{5}+2\implies y=-\cfrac{1}{5}x+\cfrac{7}{5} \\\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{5}}{5(y)=5\left( -\cfrac{1}{5}x+\cfrac{7}{5} \right)}\implies 5y=-x+7\implies \blacktriangleright x+5y=7 \blacktriangleleft$

Simplify 5/8x -2y +3/4x-8y

AleksandrR [38]

Answer:

On simplification, $\frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$

Step-by-step explanation:

Here, the given expression is:

$\frac{5}{8}x - 2y + \frac{3}{4}x -8y$

Now, we can perform operations only on LIKE TERMS,

So, in this expression, separate the like terms we get:

$\frac{5}{8}x - 2y + \frac{3}{4}x -8y = \frac{5}{8}x + \frac{3}{4}x - 2y -8y\\= (\frac{5}{8} + \frac{3}{4})x -(2y + 8y) = (\frac{5 + 3(2)}{8}) x - (10y)\\= (\frac{11}{8}) x - 10y\\\implies \frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$

Hence, on simplification, $\frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$
