Step Type Explanation Answer

1

Problem

Solve the linear equation for x:
\$ (-3x - 2)/(x + 2) = -7 \$

2

Step

By using cross multiplication we get

-3x - 2 = -7(x + 2)

3

Step

After simplification we get

-3x - 2 = -7x - 14

4

Step

Move "x" variable terms right hand side and constant terms left hand side

-3x + 7x = -14 + 2

5

Step

After simplefication we get

4x = -12

6

Step

Dividing on both sides by "4" we get

\$ \cancel(4)/\cancel(4)x = - \cancel12^3/\cancel4^1 \$

7

Step

After cancellation we get

x = - 3
