Question

Hakeem subtracted 8 from a number, then multiplied the difference

by
4/5. The result was 20. Write and solve an equation to find the
number, x.

Answer 1

12

Explanation:

(×-8)5=20

(5×-40)=20

5×(-40+40)=(20+40)

5×=60

5×÷5=60÷5

×=12

Answer 2

9514 1404 393

Answer:

33

Explanation:

8 subtracted from the number is ...

x -8

and 4/5 of that value is ...

4/5(x -8)

The equation will say this result is 20:

4/5(x -8) = 20

__

Multiplying by 5/4, we get ...

x -8 = 25

x = 33 . . . . . . add 8

The number, x, is 33.
