Best ResponseYou've already chosen the best response.0However, you can subtract x from both sides and subtract 3 from both sides to get 0 = 0 Then you'll know that the solutions are infinite.

Best ResponseYou've already chosen the best response.0subtract 0.8x from both sides to end up with 0.2x = 72 Divide both sides by 0.2 to get x = 72/0.2 x = 360
