Question

Solve for x. 7x + 10 = 3x + 120

Answer 1

Answer:

x = 27.5

Step-by-step explanation:

Reorder the terms: 10 + 7x = 3x + 120

Solving 10 + 7x = 120 + 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. 10 + 7x + -3x = 120 + 3x + -3x

Combine like terms: 7x + -3x = 4x 10 + 4x = 120 + 3x + -3x Combine like terms: 3x + -3x = 0 10 + 4x = 120 + 0 10 + 4x = 120

Add '-10' to each side of the equation. 10 + -10 + 4x = 120 + -10

Combine like terms: 10 + -10 = 0 0 + 4x = 120 + -10 4x = 120 + -10

Combine like terms: 120 + -10 = 110 4x = 110

Divide each side by '4'. x = 27.5
