4 - w = 7
subtract 4 from each side
4 - 4 - W = 7 - 4
- W = 3
divide both sides by - 1 ( remember, the implied coefficient of w is - 1 )
(- 1/- 1)w = 3/- 1
w = - 3
=======check in original equation
4 - (- 3) = 7
4 + 3 = 7
7 = 7

7-4w=10 7=10+4w 7-10=4w -3=4w -3/4=w
It is an equation and the value of w is 3 2w - 11 + 4w = 7 6w - 11 = 7 6w = 7 + 11 6w = 18 w = 3
3/4w+8=1/3-712(3/4w+8)=12(1/3w-7)9w+96=4w-849w-4w+96=4w-4w-845w+96=-845w+96-96=-84-965w=-1805w/5=-180/5w=-36
w + 3 = 4w - 6 9 = 3w w = 3
w = 5
7-4w=10 7=10+4w 7-10=4w -3=4w -3/4=w
It is an equation and the value of w is 3 2w - 11 + 4w = 7 6w - 11 = 7 6w = 7 + 11 6w = 18 w = 3
If: -4w = 14 Then: w = -3.5
3/4w+8=1/3-712(3/4w+8)=12(1/3w-7)9w+96=4w-849w-4w+96=4w-4w-845w+96=-845w+96-96=-84-965w=-1805w/5=-180/5w=-36
w + 3 = 4w - 6 9 = 3w w = 3
8w-4w=20 simplifies to 4w=20 and then dividing both sides by 4 we have w=20/4=5
w=4.5
w = 5
15
7w - 4w - 6w = (7 - 4 - 6)w = -3w
w=8
w = 70.25
