​

Answer 1

Given,

2x+y=9--------------------------(1)

3x−y=6--------------------------(2)

Adding eq

n

(1) and eq

n

(2)

2x+y=9 + (3x−y=6) =9+6

x=

5

15

=3

We get, x=3mark me brainlist

Answer 2

Answer:

$2x + y = 9 \\ 3x - y = 6 \\ by \: adding \: both \: \: equations \: we \: get \: x \: value \: that \: is \: \\ 2x + 3x + y - y = 9 + 6 \\ 5x - 0 = 15 \\ 5x = 15 \\ x = 15 \div 5 \\ x = 3$
