Answer 2

hey user !!

Answer:

x = 6, y = 1

step by step explanation

2x = 9+3y

2x = 9+3yx = 9+3y/2

then putting the value of x in 2nd equation

=>2x+y = 13

=>2×9+3y/2 + y = 13

=>9+3y+y = 13

=>9+4y = 13

=>4y = 13 - 9

=>4y = 4

=>y = 4/4

y = 4/4y = 1

y = 4/4y = 1now in equation 2nd

=>2x + y = 13

2x + y = 13now putting y=1

=>2x + 1 = 13

=>2x = 13 - 1

=2x = 12

2x = 12x = 12/2

2x = 12x = 12/2x = 6
