    Step-by-step explanation:

    2x+y=18 ... equn. (1)

    2x+3y=42 ... equn. (2)

    to eliminate x, subtract equn. (2) from equn. (1)

    0-2y=-24

    divide via by - 2

    -2y/-2=-24/-2

    y=12

    to solve for x, put y in any equation.

    from equn. (1) 2x+y=18

    2x+12=18

    subtract 12 from both sides

    2x=6

    divide via by 2

    2x/2=6/2

    x=3
