  1. Find the given value of variable:
    3x + 7 = 5x + 9


    Step 1 :  

    The given equation is: 3x + 7 = 5x + 9



    Step 2 :  

    subtract by -7 on both sides
    3x + 7 -7 = 5x + 9 -7
    3x = 5x + 2



    Step 3 :  

    Bring the variables on one side
    3x - 5x = 2
    -2x = 2
    x = -1.



    Answer  :  

    The value of x = -1.



  2. Find the value of variable:   3x2 - x + 1 = x2 - x + 9



    Step 1 :  

    The given variable equation is 3x2 - x +1 = x2 - x + 9



    Step 2 :  

    Subtract by -1 on both sides
    3x2 - x + 1 - 1 = x2 - x + 9 -1



    Step 3 :  

    Bring the variables on one side
    3x2 - x - x2 + x = 8
    2x2 = 8
    x2 = 4
    x = $\pm$ 2.



    Answer  :  

    The value of x is +2 or -2.
