Answer:
41
Step-by-step explanation:
(2/5) x - 8 = 9 - ( 3/5 )
First you need to multiply everything with inversely proportional number of 2/5 to get x alone.
(2/5) x - 8 = 9 - ( 3/5 ) / × 5/2
x - (8 × 5/2) = 9 × 5/2 - (3/5 × 5/2)
x - 40/2 = 45/2 - 15/10
Now you switch 40/2 on the other side, but when you do this, you need to change it's sing (minus to plus). We do that so x can be alone on one side.
x = 45/2 - 15/10 + 40/2, contracted, it look like this:
x = 22,5 - 1,5 + 20
and x = 41
