Question

Solve each given equation and show your work. Tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither.

(a) 6x + 4x - 6 = 24+9x

(b) 25 - 4x =15 - 3x+10-x

(c) 4x + 8 = 2x + 7 + 2x -20

please hurry it's due today!!!!

Answer 1

a)6x+4x-6=24+9x

10x-9x=24+6

x=30

one solution

b)25-4x=15-3x+10-x

25-25=-4x+4x

0=0

infinite solutions

c)4x+8=2x+7+2x-20

4x-4x=-20+7-8

0=19

no solutions
