Answer:
Step-by-step explanation:
Simplifying
7x = -3x + -60
Reorder the terms:
7x = -60 + -3x
Solving
7x = -60 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
7x + 3x = -60 + -3x + 3x
Combine like terms: 7x + 3x = 10x
10x = -60 + -3x + 3x
Combine like terms: -3x + 3x = 0
10x = -60 + 0
10x = -60
Divide each side by '10'.
x = -6
Simplifying
x = -6
