Question

Solve: -2x - 15 = 6x + 9

3

-3

-1

6

Answer 1

-2x - 15 = 6x + 9

Add 15 to both sides:

-2x = 6x + 24

Subtract 6x to both sides:

-8x = 24

Divide -8 to both sides:

x = -3

Answer 2

Solve: -5x = 30

6

-6

25

35

Answer 3

you can even check your answer to make sure

-2x - 15 = 6x + 9
-2(-3) - 15 = 6(-3) + 9
6 - 15 = -18 + 9
-9 = -9 (correct)
=============

-5x = 30 --- divide both sides by -5
x = 30/-5
x = -6

Answer 4

Given the equation 3x - 3 = 6x + 1, select the reasoning that correctly solves for x.

Add 3, subtract 3x, then divide by -3.

Add 3, subtract 6x, then divide by 3.

Subtract 1, subtract 3x, then divide by 3.

Subtract 1, subtract 6x, then divide by -3.

Answer 9

3x - 3 = 6x + 1 --- subtract 1
3x - 4 = 6x -- subtract 3x
-4 = 3x -- divide by 3
x = -4/3
===============
-4 (2x - 1) = -6 (x + 2) - 2 --- distribute through the parenthesis
-8x + 4 = -6x - 12 - 2 --- combine like terms
-8x + 4 = -6x - 14 -- subtract 4
-8x = -6x - 18 -- add 6x
-2x = -18 -- divide by -2
x = -18/-2
x = 9
