2.3.PS-17 Question Help - Julio says, "If you subtract 14 from my number and multiply the difference by -2, the result is -40." What is Julio's number?

please and Thank You​

Answer 1

34

Explanation:

-2(x - 14) = -40 Distribute the -2

-2x + 28 = -40 Subtract 28 from both sides

-2x = -68 Divide both sides by -2

x = 34

Check:

34- 14 = 20

-2(20) = -40
