Solve for x .
2x + 9 = 35 Subtract 9 from both sides of the equation.
2x = 35 - 9
2x = 26 Divide both sides of the equation by 2 .
x = 26 / 2
x = 13
Solve for p .
3 + |1 + p| = 12
I don't really know the best way to do these, but someone else probably does.
Solve for n .
(2n - 3) / 5 = 5 Multiply both sides of the equation by 5 .
2n - 3 = 5 * 5
2n - 3 = 25 Add 3 to both sides of the equation.
2n = 25 + 3
2n = 28 Divide both sides of the equation by 2 .
n = 28 / 2
n = 14
Solve for d .
6(d + 1) - 2d = 54 Distribute the 6 to both terms in parenthesees.
6d + 6 - 2d = 54 Combine 6d and -2d to get 4d .
4d + 6 = 54 Subtract 6 from both sides.
4d = 48 Divide both sides by 4 .
d = 12
Solve for y .
-140 = 18 + 4(5y - 2) Distribute the 4 to both terms in parenthesees.
-140 = 18 + 20y - 8 Combine 18 and -8 to get 10 .
-140 = 10 + 20y Subtract 10 from both sides.
-150 = 20y Divide both sides by 20 .
-7.5 = y
