Solve for 9(p-4)=-18
statuscvo [17]
9(p - 4) = -18

Simplify our equation by multiplying the parenthesis out.

(9 × p) + (9 × -4) = -18

Simplify.

9p +  (-36) = -18

Get rid of parenthesis.

9p - 36 = -18

Now, since we're trying to isolate "p," we need to add 36 to both sides.

9p - 36 + 36 = -18 + 36

Simplify.

9p = 18

Divide both sides by 9.

9p ÷ 9 = 18 ÷ 9

Simplify.

p = 2
