For which equation would x = 12 not be a solution?
12x = 144
5x = 60
8x = 96
6x = 84

6x=84

Step-by-step explanation:

6x12 doesnt equal 84

You want to put anything with x on one side, and anything without x on the other side.so 2.14x - 12.18 = -5.76take the -12.18 to the other side by adding 12.18 on both sides2.14x - 12.18 + 12.18 = -5.76 + 12.182.14x = 6.42then divide both sides by 2.14which givesx = 3
