Question

Julio ​says, "If you subtract 16 from my number and multiply the difference by −6​, the result is −138​." What is Julio​'s ​number?

Answer 1

-7

Explanation:

use X to represent the unknown number

(x-16) -6=-138

-138/6= -23

(x-16)=-23

add 16 to both sides

x= -7

Julio's number is -7

you can also plug it back into the formula to prove it is right
