9 8w - 17 = -89 ie 8w = -89 + 17 = -72 w = -9
W=5
5w + 9.9 = 4.8 + 8w5w - 5w + 9.9 - 4.8 = 4.8 - 4.8 + 8w - 5w5.1 = 3w5.1/3 = 3w/31.7 = w
8x-8w = 0
Oh, what a happy little math problem we have here! To factor w^2 + 8w + 12, we're looking for two numbers that multiply to 12 and add up to 8. Those numbers are 2 and 6. So, we can rewrite the equation as (w + 2)(w + 6). Just like that, we've created a beautiful factorization!
If: 8w = 44 then w = 5.5
8w - 12 = -48w = 8w = 1
9 8w - 17 = -89 ie 8w = -89 + 17 = -72 w = -9
-36 + 2w = -8w + w -36 + 2w = -7w -36 = -7w - 2w -36 = -9w w = -36/-9 = 4
W=5
w = 5
5w - 5 = 8w - 25 -5 + 25 = 8w - 5w 20 = 3w 6 2/3 = w
Simplified, this is equal to 19 + 8w = 67 Therefore, 8w = 67 - 19 = 48 Therefore, w = 48/8 w = 6
8w-4w=20 simplifies to 4w=20 and then dividing both sides by 4 we have w=20/4=5
2w + 16 = - 6w - 8 2w + 16 + 6w = - 8 8w + 16 = - 8 8w = - 8 - 16 8w = - 24 w = - 3
82
A simple equation, true when w = -4
