Answer:

Resulting equation: [tex]-7x+24=3[/tex]

[tex]x=3, y=-1[/tex]

Step-by-step explanation:

[tex]2x+3y=3\dots(1)\\y=8-3x\dots(2)\\[/tex]

substitute the value of [tex]y[/tex] in equation [tex](1)[/tex]

[tex]2x+3(8-3x)=3\\2x+24-9x=3\\-7x+24=3\\-7x=3-24\\-7x=-21\\x=3\\y=8-3x\\y=8-3\times3\\y=8-9\\y=-1[/tex]
