Answer:

x=−1

Step-by-step explanation:

7x+4=x−2

We can solve the system of equations by adding/subtracting and dividing both sides of the equations by the same factor.

Steps to solve:

1. Add/subtract to both sides to isolate x:

7x+4−4=x−2−4

7x=x−6

2. Add/subtract to both sides to combine like terms:

7x−x=x−6−x

6x=−6

3. Divide both sides by the same factor to solve for x:

6

6x

=

6

−6

x=−1
