2x+3=x+5

Since x contains the variable to solve for, move it to the left-hand side of the equation by subtracting x from both sides.
2x+3-x=5

Since 2x and -x are like terms, add -x to 2x to get x.
x+3=5

Since 3 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 3 from both sides.
x=-3+5

Add 5 to -3 to get 2.
x=2
