Answer: x = -3/2Step-by-step explanation: I am assuming that you want to solve for x.To solve for x, we need to isolated x on one side-2x = 4x + 9Subtract 4x from both sides-2x - 4x = 4x + 9 -4xSimplify-6x = 9x = -9/6x = -3/2As always, don't forget to check your work:-2x = 4x + 9-2(-3/2) = 4(-3/2) + 9-3 = -12 + 9-3 = -3, so our answer is correct.Hope this helps.Cheers,Andy
