You want to get all the terms with "x" on the same side.
First, let's remove the 4 from the left side, but make sure you do the same thing on the right side to keep the equation balanced.
x + 4 - 4 = 2x + 3 - 4
x + 0 = 2x - 1
x = 2x - 1
Now, let's move the 2x over to the left side (to get all the x's together) by adding a -2x to both sides.
-2x + x = -2x + 2x - 1
-x = 0 - 1
-x = -1
Finally, multiply both sides by -1 to get x completely by itself.
(-1)(-x) = (-1)(-1)
x = 1
The final answer is x = 1.

Subtract 2x from both sides:
-x+4=3
Subtract 4 from both sides:
-x=-4
Divide -1 from both sides:
x=1
Check:
1+4=2(1)+3
1+4=2+3
5=5

x+4 = 2x+3
4 = 2x+3 -x
4 = x +3
4-3 = x
1 = x
