What values of b satisfy 3 (2b + 3) 2 = 36?

To find the answer, you need to solve for b.

2 (2b + 3) = 12 divide both sides by 3

2b + 3 = 6 divide both sides by 2

2b = 3 subtract 3 from both sides

b = 1.5 divide both sides by 2

b = 1.5 satisfies the equation. if you plug 1.5 in, you get that the equation is true.
