Solve for b.

–12 = 4(b − 15) − 16

b =

b = 16

Step-by-step explanation:

–12 = 4(b − 15) − 16

Add 16 to each side

–12+16 = 4(b − 15) − 16+16

4 = 4 (b-15)

Divide each side by 4

4/4 = 4(b-15)

1 = b-15

Add 15 to each side

1+15 = b-15+15

16 = b

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
