Question

Peter has to use the following information to find the original number: "If you double a number and then add 36 you get 4/11 of the original number." Write and solve an equation to find the original number.

Answer 1

-22

Explanation:

2x + 36 = 4/11 x

2x - 4/11 x = - 36

18/11 x = - 36

x = ((-36) x 11) / 18 = - 22
