y=1/4x-1
1/2y=x-2
This is systems of Equations
please work out the problem and explain it

  • algebra - ,

    I would multiply the 2nd by 2 to get
    y = 2x - 4
    now we can equate y = y
    2x-4 = (1/4)x - 1
    times 4
    8x - 16 = x - 4
    7x = 12
    x = 12/7
    then y = 24/7 - 4 = -4/7

    x = 12/7, y = -4/7
