6(2x - 11) + 15 = 21 Write the steps you will use to solve the equation and explain each step.

dk the steps to solve this

6(2x + -11) + 15 = 21

Reorder the terms:

6(-11 + 2x) + 15 = 21

(-11 * 6 + 2x * 6) + 15 = 21

(-66 + 12x) + 15 = 21

Reorder the terms:

-66 + 15 + 12x = 21

Combine like terms: -66 + 15 = -51

-51 + 12x = 21

Solving

-51 + 12x = 21

Solving for variable 'x'.

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

Add '51' to each side of the equation.

-51 + 51 + 12x = 21 + 51

Combine like terms: -51 + 51 = 0

0 + 12x = 21 + 51

12x = 21 + 51

Combine like terms: 21 + 51 = 72

12x = 72

Divide each side by '12'.

x = 6

Simplifying

x = 6

6

Step-by-step explanation:

6(2x-11)+15=21

=> 12x-66+15=21

=>12x-51=21

=>12x=21+51

=>12x=72

=>x=72÷12

=>x=6
