Write an equation to solve the following. Show all your work, including the steps for solving the equation and checking your answer.

-4 times a number plus 16 is - 116. Find the number. Answer:

Equation

-4x + 16 = - 116

solve for x

-4x + 16 = - 116

subtract 16 to both sides

-4x + 16 - 16 = - 116 - 16

simplify

-4x = - 132

divide - 4 to both sides

-4x/-4 = - 132/-4

simplify

x = 33

answer: the number is 33
