2(6x+9−3x)=5x+21 PLEASE HELP !!

x=3

Step-by-step explanation:

Simplifying

2(6x + 9 + -3x) = 5x + 21

Reorder the terms:

2(9 + 6x + -3x) = 5x + 21

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

2(9 + 3x) = 5x + 21

(9 * 2 + 3x * 2) = 5x + 21

(18 + 6x) = 5x + 21

Reorder the terms:

18 + 6x = 21 + 5x

Solving

18 + 6x = 21 + 5x

Solving for variable 'x'.

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

Add '-5x' to each side of the equation.

18 + 6x + -5x = 21 + 5x + -5x

Combine like terms: 6x + -5x = 1x

18 + 1x = 21 + 5x + -5x

Combine like terms: 5x + -5x = 0

18 + 1x = 21 + 0

18 + 1x = 21

Add '-18' to each side of the equation.

18 + -18 + 1x = 21 + -18

Combine like terms: 18 + -18 = 0

0 + 1x = 21 + -18

1x = 21 + -18

Combine like terms: 21 + -18 = 3

1x = 3

Divide each side by '1'.

x = 3

x=3

Step-by-step explanation:

(12x+18-6x)=5x+21

6x+18=5x+21

x+18=21

x=3
