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
