Find
w in the following equation;

__3w__-

__w-3__=

__w__

7 2 5

__solution__

__3w__-

__w-3__=

__w__

7 2 5

The LCM of 5, 7 and 2 is 70. So, we multiply by 70 throughout

70x

__3w__- 70(__w-3)__=__w x 70__
7 2 5

^{10}

__3w__-

^{35}

__w-3)__=

__w__x

10 x 3w - 35(w-3) = w x 14

30w
- 35w + 105 = 14w

-5w + 105 = 2w

105 = 2w + 5w

105
= 7w

__105__=

__7w__

7 7

15
= w

__Hence w = 15__
