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
