Answer:
After finding the solution of given equations by elimination method
-3x-3y=12
-9x+3y=-24
we get the value of x=1 and y= -5
Step-by-step explanation:
is eq A
is eq B
To find out value of x and y we will use elimination method
To find value of x add eq A and eq B
Now to find value of y put x=1 in eq A
so the value of
x= 1
and
y= -5
For checking the solution
putting value of x and y in eq A
Hence proved
Putiing value of x and y in eq B
Hence proved
