Answer 6

2(x+4)=30

Divide each term in the equation by 2.
(2(x+4))/(2)=(30)/(2)

Remove the common factors that were cancelled out.
(x+4)=(30)/(2)

Remove the parentheses around the expression x+4.
x+4=(30)/(2)

Remove the common factors that were cancelled out.
x+4=15

Since 4 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 4 from both sides.
x=-4+15

x=11
