Otherwise, you only need the initial and finak value to find the difference.

If x+4/4 = y+7/7 then x/4=___

muminat

Please, enclose those binomials x+4 and y+7 inside parentheses:

(x+4) / 4 = (y+7) / 7. Find (x/4).

Let's solve the above equation for x:

x+4 = 4(y+7)/7. Then x = 4(y+7) / 7 - 4

Last, divide all 3 terms by 4: x/4 = (y+7) / 7 - 1 (answer)

y + 7 - 7
You could also type this as x/4 = ------------- = y/7
