Solve the linear equation. Solve for x and y
y=-3/4x + 1/4
y=3/4x - 3/4

  • Math - ,

    add the two equations to get y alone:
    y = -3/4x + 1/4
    y = 3/4x - 3/4
    --------------------------
    2y = -2/4
    y = -1/4
    then substitute this value of y to either of the equations and solve for x. in this case let's substitute this to the first give equation:
    y = -3/4x + 1/4
    -1/4 = -3/4x + 1/4
    -1/4 - 1/4 = -3/4x
    (-2/4 = -3/4x)*4
    -2 = -3x
    x = 2/3

    hope this helps~ :)
