    1. You have the following equations:

    y=-2x+5 (i)

    3x-4y=2 (ii)

    2. You must substitute the equation (i) into the equation (ii), as below:

    3x-4y=2

    3x-4 (-2x+5) = 2

    3x+8x-20=2

    11x-20=2

    3. Now, you must clear the variable "x":

    11x=2+20

    x=22/11

    x=2

    4. You have the value of "x", so you can find the value of "y". When you substitute x=2 into the equation (i), you obtain:

    y=-2x+5

    y=-2 (2) + 5

    y=-4+5

    y=1

    5. Therefore, the answer is:

    x=2

    y=1
