    Answer:

    The answer to your question is (3, 0)

    Step-by-step explanation:

    Data

                  4x  +  2y  = 12                 Equation l

                    x  –    y   = 3                   Equation ll

    Process

    To solve this problem use the elimination method

    1.- Multiply equation ll by 2

                  4x  +  2y  =  12

                  2x  –  2y  =    6

                  6x      0   = 18

    2.- Solve for x

                            6x = 18

                              x = 18/6

                              x = 3

    3.- Substitute x in equation ll to find y

                    3  –  y  = 3

    -Solve for y

                        -y = 3 – 3

                         y = 0

    4.- Write the solution

                       (3, 0)
