Answer: 2x + 30 = 7x
Step-by-step explanation: Simplifying
2x + 30 = 7x
Reorder the terms:
30 + 2x = 7x
Solving
30 + 2x = 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
30 + 2x + -7x = 7x + -7x
Combine like terms: 2x + -7x = -5x
30 + -5x = 7x + -7x
Combine like terms: 7x + -7x = 0
30 + -5x = 0
Add '-30' to each side of the equation.
30 + -30 + -5x = 0 + -30
Combine like terms: 30 + -30 = 0
0 + -5x = 0 + -30
-5x = 0 + -30
Combine like terms: 0 + -30 = -30
-5x = -30
Divide each side by '-5'.
x = 6
Simplifying
x = 6
