8u = 3u + 35
Transpose 3u
8u - 3u = 3u + 35 - 3u
5u = 35
Divide both sides of the equation by 5
5u / 5 = 35 / 5
u = 35 / 5
u = 7

8u = 3u + 35
Minus 3u from both sides
8u = 3u + 35
-3u -3u
5u = 35
divide by 5
5u = 35
/5 /5
u = 7

Subtract 3u from both sides
5u=35
u=7

8u=3u+35 or 8u-3u=35 or 5u=35 or u=7

Try subtracting 3U from both sides and see what you get.
