two there sorry for disturbing

Answer 2

Step-by-step explanation:

2x-3y=1 ----eq.1

x+y=-2. ----eq.2

By substitution Method:

x=-2-y. ------eq.3

By putting the value of x in eq. 1:

2x-3y=1

2(-2-y)-3y=1

-4-4y-3y=1

-4-7y=1

-7y=1+4

-7y=5

y=-5/7

By putting the value of y in eq.3:

x=-2-y

x=-2-(-5/7)

x= -2+5/7

x=-9/7

Hope it helps you!!!!
