Question

plz tell me as soon as possible ​

Answer 1

Answer:

x= - 2

y= 4

Step-by-step explanation:

10x+7y=8.......(1). Taking the standard form

-5x+2y=18.....(2)

Multiple equation 2 by 2

-10x+4y=18....(3) add eq 3 and 1

10x+7y=8

By solving we get y=4

And putting the value in eq 1

We get x= - 2
