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
7
divide by 2 on both sides.
3/2
x=1.5
