I need to find the linear system for the equations 4x+3=y and x=y-2
Any help at all would be great!
And please show me how you did it if possible, thanks!

    4 x - 1 y = -3
    1 x - 1 y = -2
    -------------- subtract
    3 x - 0 y = -1
    x = -1/3
    then y = 4 (-1/3) + 3
    y = -4/3 + 9/3
    y = 5/3
    so (-1/3 , 5/3)

    check
    4(-1/3) + 3 = -4/3+9/3 = 5/3 right
    -1/3 = 5/3 - 2
    -1/3 = 5/3 -6/3 right
