Solve the proportion. 2/5=x-4/4
Answered by DL
2/5 = x-4/4
2/5 = x-1
2/5(+1) = x-1(+1)
2/5(+5/5) = x
7/5 = x
Answered by Reiny
I have a sneaking suspicion that you meant
2/5 = (x-4)/4
since no respectable textbook would write 4/4 in a question.

if so, then
5x - 20 = 8
5x = 28
x = 28/5

Thank you for your help. I am sorry I couldn't fill it in correctly, but the problem doesn't read 2 divided by 5 equals x-4 divided by 4. They are actually fractions. So it is 2 numerator and 5 denominator. Does this change the answer?
