    To get the answer for this problem, first get all the x's on one side of the equation.  You do that by subtracting 2x from each side.  That gets you

     

    -x+4 = 3 (because x-2x is -x)

     

    Then you want to get all the numbers on the other side of the equation.  To do that, subtract 4 from each side.  That gets you

    -x = -1 (because 3-4 is -1)

    Now to make your x positive, multiply both sides by -1.  That gets you

    x = 1

    And that's your answer.

    Here to solve for x, subtract x from each side. In doing this, the x on the left side will cancel out. You are now left with 4=x+3. Now subtract 3 from each side. x=1.

    X=1 because 2x1+3=5

    1+4=5
