Feb 7, 2016

Put the r's to one side of the equation and solve.

#### Explanation:

$- 3 r - 8 = - 5 r - 12$

$- 3 r + 5 r = - 12 + 8$

$2 r = - 4$

$r = - 2$

Practice exercises:

1. Solve for x in the following equations. Keep in fractional form when necessary.

a) 2x = -14

b) $\frac{x}{3}$ + 9 = 22

c) 3x + 5 = -4x - 11

d) 2(3x - 6) = -(5 + x)

Good luck!
