You already know that y equals -4. It says that x equals 3, so multiply the -4 by 3 and because it has a negative number and a positive number it will equal -12. Remember anytime you see a letter after a number it means multiply. The complete problem should be -10 because 2 is a whole number you subtract it from -12. Hope that helped you out some.

Answer:
Step-by-step explanation:
EB = 1.25×BC
x+5 = 1.25(x+1)
x+5 = 1.25x + 1.25
3.75 = 0.25x
x = 15
(b+8) * 5b^2
__________
b * (b^2-64)
(b+8)*5*b^2
__________
b*(b-8)*(b+8)
5b
___
(b-8)
Check, say b = 1: my result is 5/(-7), the original: 9/1:-63/5 = -45/63=-5/7! Yup!
