    x=2. y=1/2

    Step-by-step explanation:

    4x-2y=7. Equation 1

    x+2y=3. Equation 2

    Add the two equations

    (4x+x) + (-2y+2y) = 7+3

    5x+0=10

    5x=10 divide both sides by 5

    X=2

    Substitute x=2 in equation 2

    2+2y=3

    2y=3-2

    2y=1. Divide both side by 2

    Y=1/2
