Answer:
(8,8)
Step-by-step explanation:
First simplify like terms (things with the same letter):
3g + 7g + 8 = -10 + g
10g + 8 = -10 + g
Next we should take g off both sides:
9g + 8 = -10
Next isolate 9g by taking 8 off both sides:
9g = -18
Next divide both sides by 9 to find the value of g:
g = -2
You can cross multiply and the answer would be 100/9
9/10=10/k
100=9k
k=100/9
Percent increase is
100(new/old - 1)
Here that's
100(26/22 - 1) = 200/11 ≈ 18.2
