In Ex 1: LCD = 12

YOU TRY!!!!!!!!! k = 20 m = -4 or 1 x = -3, -8 Cannot be m = 1 because it is an excluded value!! (Makes the bottom of the fraction 0)

Solving Rational Equations Practice Complete Page 37 When complete check answers on next page…

Practice Answers 1. a = -3 2. b = -9/4 3. x = 4.1 4. k = 1/2 5. m = -3/2 6. x = -2 7. p = -5 or 3 8. a = 5 9. b = 1 10. k = -1
