Answer:

y = 5/2 , x= 7/2

Step-by-step explanation:

5x - 3y = 10…....(1)

3x + 3y = 3......(2)

solving by elimination, we subtract equation (2) from equation (1)

so, 2x = 7

dividing both sides by 2

x= 7/2

substitute x=7/2 for the value of y in equation (1)

5(7/2) - 3y = 10

multiply both sides by 2

35 - 6y = 20

rearranging

-6y = -15

dividing both sides by -6

y = 5/2
