Question

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:

Answer 1

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
