HELP! How do I solve for x:

4x+2=3x+9

  • math - 6th grade - ,

    subtract 3x+2 from both sides and you have

    4x+2 -3x-2 = 3x+9 -3x-2
    x = 7

  • math - 6th grade - ,

    4x+2=3x+9

    Subtract 2 from both sides of the equation.

    4x = 3x + 7

    Subtract 3x from both sides

    x = 7

  • math - 6th grade - ,

    4x+2=3x+9
    Move 3x to the other side so it will become -3x ( 4x-3x) same with the constant number ( 9-2) . Just combine the constant and the number that has coefficient.

    Solution: 4x+2= 3x+9
    4x-3x=9-2
    X=7
