Question

2x+y=9
x+y=7

solve this equation

by elimination method

im brainlist best answer​

Answer 1

$2x+y=9-----(i)\\x+y=7-----(ii)$

Subtracting both equations we get ;

$2x+y = 9\\x +y = 7\\------\\x=2$

This is because due to subtraction x, y and 7 becomes negative and y got eliminated.

Putting value of x in (ii) equation ;

$2+y=7\\y=7-2\\y=5$
