The football team gained 9 yards so that would be a positive number. Then they lost 22 yards so that would be a negative number. If you go to the left of the number line it would be a negative number. If you go to the right of the number line it would be a positive number. If you go to the left the numbers are getting smaller. If you go to the right the numbers are getting bigger. Hope this helps
L = w - 5
2*l + 2*w = 26
2*(w - 5) + 2*w = 26
2w - 10 + 2w = 26
4w = 36
w = 9
l = w - 5
l = 9 - 5
l = 4
