Question

Solve for x. 7x = -42 Solve for x. x + y -7

Answer 1

Answer:

1) -6

2) x = -y +7 if you set all terms equal to zero.

Step-by-step explanation:

1) Isolate x by dividing -42 by 7. x = -6

2) Set the entire expression equal to zero.

x + y -7 = 0

Isolate x on one side of the equation. Remember to change signs when moving terms across the equal sign.

x = -y +7 if  the original expression is set equal to zero.
