Question

Explain how to solve: 3(9+4a)−19=32
step by step

Answer 1

First, distribute the 3 on the left side of the equation: 3 * 9 + 3 * 4a - 19 = 32

Next, combine like terms on the left side of the equation: 27 + 12a - 19 = 32

Add 19 to both sides of the equation to isolate the variable term: 27 + 12a = 51

Subtract 27 from both sides of the equation to isolate the variable term: 12a = 24

Divide both sides of the equation by 12 to solve for the value of "a": a = 2

So the solution to the equation is "a = 2".
