Solve the following equation: 96= -6( -4-3y) a. y=2 b.y=4 c.y= -2 d. y=6

tankabanditka [31]

96 = -6 * (-4 - 3y) <== It's easiest to solve when the y is on the right
 ↓
-6 * (-4 - 3y) = 96 <== Multiply the -6 by everything inside the
 parentheses
 ↓
 24 + 18y = 96 <== Subtract the 24 from both sides
↓
18y = 72 <== Divide both sides by 18
↓
y = 4

The correct answer is choice B. y = 4.
Hope that helped =)
