Answer 2

Step-by-step explanation:

5x-3y=2..…........…........….....….....1)

4x+7y=-3.......……………………………2)

In equation 1

X=(2+3y)/5…………………………3)

Put the value of x in equation 2

4(2+3y)/5+7y=-3

(8+12y)/5+7y=-3

(8+12y+35y)/5=-3

8+47y=-15

47y=--7

y=-7/47

Put the value of y in equation 3

X=[2+3×(-7/47)]/5

X=(2-21/47)/5

X=[(94-21)/47]/5

X=73/47/5

X=73/215
