Answer:

7. Xyrex = x
brother = b
Xyrex is five times as old as his brother = 5b
Difference between their ages is 8 years = x-b=8

x - b = 8
5b - b = 8
4b = 8
b = 8/4

b = 2 y/o

x = 5b
x = 5(2)

x = 10 y/o

8. x / x + 2 = 59

[tex]\frac{x}{x + 2}(x + 2) = 59(x + 2)[/tex]

x = 59 (x + 2)

x = 59x + 118

x - 59x = 118

-58x = 118

x = -59/29

9. 41 - 3x = x + 5

-3x - x = -41 + 5

-4x = -36

x = 9

10. 2c - 2 = 72

2c = 72 + 2

c = 74 kg
