    Answer:

    (-5, -2)

    Step-by-step explanation:

    3x+4y=-23

    x=3y+1

    since we have what x is, we need to subsitute

    3( 3y+1) + 4y= -23

    no we need to multiply the number inside the parenthesis by 3

    9y + 3 + 4y= -23

    combine like terms ( add the numbers or variables that look alike)

    9y+4y is 13y

    13y+3= -23

    since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding

    13y+3-3=-23-3

    13y= -26

    now we divide 13 on both sides to get Y alone

    13y/13= -26/13

    y= -2

    now since we have y we need to substitute it to find x

    x= 3y+1

    x= 3( -2) +1

    now we mutliply 3 with -2

    x= -6 +1

    x=-5

    those are ur answers

    y= -2

    x= -5

    hope this helped:D
