Answer:
Step-by-step explanation:
x=24+2 , x=-24+10
x=26 , x=-14
putting value , putting value of x in 4th eq.
x=26 in 3rd eq.
5(26)+7y=17 3(26)-2y=4
130+7y=17 78-2y=4
7y=-130+17 -2y=-78+4
7y=-113 -2y=-74
y=-113/7 y=74/2
y=37
put value of put value of 2nd x in 4th eq.
2nd x in 3rd eq.
5(-14)+7y=17 3(-14)-2y=4
7y=17+70 -2y=4+42
7y=87 -2y=46
y=87/7 y=-23
