in x + 16 = 30, you subtracted 16 from both sides to get 14, right? same goes with x's. in x + 23 = 2x + 45, you subtract that x from both sides so that there's only one x left. the x on the left disappears, and 2x - x = one x. so what you have now is 23 = x + 45. now just subtract 45 from both sides to get your answer hope this helped p.s. sorry if i confused you, the answer is -22 if that helps

x + 23 = 2x + 45
Subtract x from both sides.
23 = x + 45
Subtract 45 from both sides.
-22 = x

x + 23 = 2x + 45
Perform the same operation to both sides of the equation to produce the form x = number (or number = x)
x = 2x + 22 {subtract 23}
-x = 22 {subtract 2x}
x = - 22 {multiply by -1}

x+23=2x+45
23-45=2x-x
-22=x
just transpose the terms and you will get the answer.

23 - 45 = 2x - x : get all numbers on one side, all x's on the other side.
-22 = x : simplify
