Question

(1) 2x + 3y = 12 ; x - y = 1
and plZ follow​

Answer 1

Step-by-step explanation:

x-y=1

x=1+y

substuting the valilue of x in eq 1

we get

2x+3y=12

1+y+3y=12

1+4y=12

4y=11

y=11/4

valuse of y in eq 2 because it's easy for calculation

x-y=1

x-11/4=1

x=1-11/4

x=4/4-11/4

x=(-7/4)
