2x+12=4x
Make two equations, and solve for x.
1. 2x+12 = 4x 2. 2x+12 = - 4x subtract 2x from both sides
12=2x 12 = - 6x
6=x - 2=x
plug in the x values to know if they are the solution for the eqaution.
2 (6) + 12 = 4 (6) 2 (-2) + 12 = - 4 (-2)
12+12 = 24 - 4+12=8
24=24 8=8
The equation is true, it's all real numbers or infinite solutions.
