Question

Solve: 2x+y=10; x-y=-1, by any​

Answer 1

Answer:

x = 3

Step-by-step explanation:

Hey this your Answer!!!!

$2x + y= 10$-----------equation 1

$x - y = -1$

$2x -2y = -2$

By elimination method:

$2x + y = 10\\\\2x - 2y = -2\\\\-2x + 2y = 2$

So we will get

$3y =12\\\\y = 12/3\\\\y = 4$

Now put the value of y in eq (2)

$x - y = -1\\x - 4 = -1\\x = 4 - 1\\x = 3$
