<span>To answer this question, you need to multiply the number inside the bracket first. Then you can move the number to the right side of the equal sign and keep the x on the left side of the equal sign. The step would be like this
2(x – 5) - 6x= -22
(2x - 10) - 6x = -22
2x - 6x = -22 +10
-4x= -12
x= -12/-4
x=3</span>

Replace x in each equation with 4:
f(x) = x^2 +2x-3 = 4^2 + 2(4) -3 = 16 + 8 -3 = 21
g(x) = x^2-9 = 4^2 -9 = 16-9 =7
Now you have values for f(x) and g(x) now you can solve for f/g and f+g:
f/g = 21 / 7 = 3
f+g = 21 + 7 = 28
