Question

When i think of a number , multiply it by 6 and subtract 120, my answer is -18. what was my number?

Answer 1

Answer:

Let X be the number you're looking for:

((X-7)*3 +6)/7=3

(3X-21+6)/7=3

(3X-15)/7=3

3X-15=21

3X=36

X=12

Answer 2

Answer:

let us think the number as x

x×6-120=-18

6x+120=-18

6x=-18-120

6x=-138

x=-138/6

x=-23
