Question

How many solutions does this equation have? 3(4x - 3) - 7x = 5x -9
A. One solution
B. infinite solutions
C. No solutions

Answer 1

3(4x - 3) - 7x = 5x - 9 --- distribute through the parenthesis
12x - 9 - 7x = 5x - 9 -- combine terms
5x - 9 = 5x - 9
0 = 0

when you get an answer such as this...0 = 0 or 5 = 5 or -2 = -2......this means there can be any number subbed in for x and it would make the equation true

Answer 2

and if you can use any number for x and it would make the equation true, what does that tell you about the equation
