    Answer:

    x=−y+19

    Step-by-step explanation:

    (x+5)(2)+(y−3)(2)=42

    Step 1: Add -2y to both sides.

    2x+2y+4+−2y=42+−2y

    2x+4=−2y+42

    Step 2: Add -4 to both sides.

    2x+4+−4=−2y+42+−4

    2x=−2y+38

    Step 3: Divide both sides by 2.

    2x

    2

    =

    −2y+38

    2

    x=−y+19
