Jax Spencer · Answer 1

Difference of a number and 17: x - 17

eight times that = 8 (x - 17)

8 (x - 17) = 30

divide both sides by 8

x - 17 = 30/8

x = 30/8 + 17 which is 20.75

Karma Guerra · Answer 2

Let the number be y;

8 * (17-y) = 30

8*17-8y=30

136-8y=30

-8y=30-136

-8y=-106

y=-106/=8

y=53/4
