I solve it see the picture....

Answer 2

Answer:

X = -4  and Y = 1

Step-by-step explanation:

X - 7Y = -11 ......(i)

5X + 2Y = -18 ........(ii)

multiply equation (i) by 5 we get 5X - 35Y = -55 ....(iii)

subtract equation (ii) from (iii)

we get -37Y = -37 ⇒ Y = 1

now put the value of Y from above in equation (i)

we get X = -4
