It's very simple!!!!!Let x be the original price of an orange.
36x + 4 = 32(x+0.2)
36x + 4 = 32x + 6.4
36x=32x+2.4
36x-32x=32x+2.4-32x
4x = 2.4
x = 0.6
So the original price of an orange is $0.6
It's very simple!!!!!!!!!!!!!!!!! I hope I can help you la!!!!!!!!!!

You should let '$x' be the original price of an orange instead of just let x.

Let x be the original price of an orange.
36x + 4 = 32(x+0.2)
36x + 4 = 32x + 6.4
4x = 2.4
x = 0.6
Original price of an orange is $0.6
36x + 4 = 32(x+0.2)
36x + 4 = 32x + 6.4
4x = 2.4
x = 0.6
Original price of an orange is $0.6
