- 3х +Зу = 12
у=х+ 4

How many solutions are there

Step-by-step explanation:

As given system of linear equations,

Hence taking 1st equation ,

-3x+3y=12    

-3(x-y)=12   ( common -3 )

now take 2nd equation ,

y=x+4

Now add these two equations, we get

x-y+ y- x=-4+4

0x+0y=0

Forgive me if i'm wrong, but i believe that the answer is B, "reflection across the y-axis followed by a reflection across the x-axis."
