Question

Peter​ says, "If you subtract 12 from my number and multiply the difference by −7​, the result is −175​." What is Peter​'s ​number​

Answer 1

The number is 37.

Explanation:

-175 ÷ -7 = 25

25 + 12 = 37

You have to work backwards from -175 by doing the reverse of what peter did to get the original number.

Answer 2

37

Explanation:

let’s say peter’s number is x

(x-12)(-7) = -175

-7x + 84 = -175

-7x = -259

x = 259/7

x = 37
