Question

. The solution of the pair of equations, 2x +y = 10, x+y = 7 is


x=3, y = 4


x=4, y= 3


x = 2, y = 5


x=5, y= 2​

Answer 1

Answer:

x=3,y=4

Step-by-step explanation:

Given equation:2x+y =10

x+y=7

Subtract the second equation from the first one..

2x+y-x-y=10-7

x=3

Now put x=3 in any equation..

U ll get y=4.
