Question

2x + 4y = 12
y = x – 3
What is the solution to the system of equations?

(–1, 8)
(8, –1)

Answer 1

2x+4y=12 divide both sides by 2 and will get x+2y=6
y=x-3 => x-y = 3

x+2y=6 subtract second from first equation
x-y=3
------------
0 3y = 3

y= 3/3 = 1

y = 1

1=x-3

x = 4
y=1

but this is interesting bc. (4,1) not is there between this choices

Answer 2

and than you check these given choices so these not are true ,right than you substitute these value of x and y in place of x and y inside equations

Answer 3

but substituted 4 and 1 will get it correct sure

please try,check these
