    Answer:

    Step-by-step explanation:

    1. first of all you have to know that we first use one of the letters x and y
    2. I will find y first using the second equation
    3. 3x +y=2 giving us y=2-3x
    4. now since we know y=2-3x we are going to find x using the fisrt equation
    5. 5x-3y=8 giving us 7/4
    6. so using x=7/4 we can workout y to get the exact answer
    7. y=2-3x replacing x with 7/4 we get y=2-3[7/4] which will = 1
    8. therefore y=1 and x=7/4

    Answer:

    Step-by-step explanation:

    5x+3y=8

    3x+y=2. × 3

    = 5x+3y=8

    9x+3y=6

    _. _. _

    ____________

    -4x=2

    =x=. -2

    ___

    4

    then, y =5×(-2/4)+3y=8

    y=….
