What is the ultimate goal when solving equations? What do you want your final answer to look like?

STALIN [3.7K]

Answer:

$\huge\boxed{\text{To get x on one side of the equation:} \ \ x = ...}$

Step-by-step explanation:

When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use $x$ .

We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.

Say we have the equation $5x+5=20$ . Our goal is to find the value of $x$ . <u>We can do this by getting x isolated on one side so we have something equal to x</u>.

We can subtract 5 from both sides and divide both sides by 5.

$5x=15\\\\x=3$

We now know the value of $x$ since it’s on one side of the equation.

Hope this helped!

HELP MEEE!! Please evaluating a compound. Inequality using a graph

Irina-Kira [14]

Answer:

$\frac{x}{2}$

Step-by-step explanation:

From the graph, we can conclude that,

$x$ is less than 2 and not including as there is a hollow circle at the mark 2.

Also, $x$ is greater than or equal to 7 including 7 as there is a solid circle at the mark 7

So, the compound inequality will be $x$

Now, the option that simplifies to the above inequality is the required answer.

Let us check the first option.

$\frac{x}{2}$

Therefore, option 1 simplifies to the above compound inequality.

So, the correct answer is option 1.

1) check if they given ordered pairs are solutions to the equation or not.

ziro4ka [17]

Answer: a) Yes
b) No

Explanation: Substitute the values of X and Y from the given points into the equation. I’ll use a) as an example:
Given point: (1,-3)
Equation: 4x-2y=10
Value of X: 1
Value of Y: -3
Substitute X and Y: 4(1)-2(-3)=10
4-(-6)=10
4+6=10 ✔︎

Therefore, the given ordered pair is a proper solution to the equation 4x-2y=10.

*You can use the same method for question b).*
