Answer:

Answer would be x = 3

Explanation:

How you would solve is first step is knowing that you want to evaluate the question and move certain numbers over to one side.

Step 1: subtract 2 (left) from 17, which gives you positive 15. So your equation should look like: -2x = -7x + 15

Step 2: take -7x and add it to -2x, which gives you positive 5x. There's a saying and not sure if you've heard it but "if you do it to one side, you do it on the other". So by adding 7x to -7x, that means they cancel each other out. Equation should look like; 5x = 15

Step 3: All you have to do now is divide both sides by 5, getting rid of the x that's attached to the 5. So, 15 divided by 5 gives you 3, so that means x = 3

Answer:

x = 3

Explanation:

In order to solve this equation, we're going to isolate x.

-2x + 2 = -7x + 17

Subtract 2 from both sides:

-2x = -7x + 17 - 2

-2x = -7x + 15

Add 7x to both sides

-2x + 7x = 15

5x = 15

Divide both sides by 5.

x = 3
