Question

1/5(x-2)=20 by which number should Marina multiply

Answer 1

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
