Question

solve the following systems of equatin.and give reason if it is not possible.2x = 13-5y 2y=17-5x​

Answer 1

Answer:

$2x + 5y = 13$

$2y - 17 + 5x = 0$

Step-by-step explanation:

$5x + 2y = 17$

5x+2y=17.......(1)

2x+5y=13......(2)

7x+7y=30.... by adding

3x-3y=4....by subtracting

21x+21y=90

21x-21y=28

solve this

42x=118

x=118/42=59/21

7x+7y=30

7(59/21)+7y=30

59+21y=90

21y=31

y=31/21
