Question

solve 9x-3=6x+18 step by step explain​

Answer 1

Step-by-step explanation:

Simplifying

9x + -3 = 6x + 18

Reorder the terms:

-3 + 9x = 6x + 18

Reorder the terms:

-3 + 9x = 18 + 6x

Solving

-3 + 9x = 18 + 6x

Solving for variable 'x'.

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

Add '-6x' to each side of the equation.

-3 + 9x + -6x = 18 + 6x + -6x

Combine like terms: 9x + -6x = 3x

-3 + 3x = 18 + 6x + -6x

Combine like terms: 6x + -6x = 0

-3 + 3x = 18 + 0

-3 + 3x = 18

Add '3' to each side of the equation.

-3 + 3 + 3x = 18 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = 18 + 3

3x = 18 + 3

Combine like terms: 18 + 3 = 21

3x = 21

Divide each side by '3'.

x = 7

Simplifying

x = 7
