Question 424772
12(2y+1)=84

Divide each term in the equation by 12.
(12(2y+1))/(12)=(84)/(12)

Simplify the left-hand side of the equation by canceling the common terms.
2y+1=(84)/(12)

Simplify the right-hand side of the equation by simplifying each term.
2y+1=7

Since 1 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 1 from both sides.
2y=-1+7

Add 7 to -1 to get 6.
2y=6

Divide each term in the equation by 2.
(2y)/(2)=(6)/(2)

Simplify the left-hand side of the equation by canceling the common terms.
y=(6)/(2)

Simplify the right-hand side of the equation by simplifying each term.
y=3
