Answer:
102
Step-by-step explanation:
i simplified the fractions into decimals just because of preference but you don't have to.
1/5 = .2
.2(x-2)=20
.2x - .4 = 20
+.4 +.4
.2x = 20.4 (if you cant tell im dividing each side by .2)
------- --------
.2 .2
x= 102
now check:
.2(102-2)=20
.2(100)=20
20=20
