Question

Write an equation and solve for x. 12x + 3 11x +9

Answer 1

Answer:

Simplifying

12x + 3 = 11x + 9

Reorder the terms:

3 + 12x = 11x + 9

Reorder the terms:

3 + 12x = 9 + 11x

Solving

3 + 12x = 9 + 11x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-11x' to each side of the equation.

3 + 12x + -11x = 9 + 11x + -11x

Combine like terms: 12x + -11x = 1x

3 + 1x = 9 + 11x + -11x

Combine like terms: 11x + -11x = 0

3 + 1x = 9 + 0

3 + 1x = 9

Add '-3' to each side of the equation.

3 + -3 + 1x = 9 + -3

Combine like terms: 3 + -3 = 0

0 + 1x = 9 + -3

1x = 9 + -3

Combine like terms: 9 + -3 = 6

1x = 6

Divide each side by '1'.

x = 6

Simplifying

x = 6
