Step-by-step explanation:
So what is 7^8*7=40353607
117649 = 7^3*7^3 too small.
7^18/ 7^9 = same answer!
(7^3)^3 = same answer!
19208= 7^4+7^5 too small.
7^4*7^5= same answer!

I would subsitute but hey, whatever floats your boat
minus y both sides in 1st equation and add to 2nd equation
-4x-y=0
<u>6x+y=6 +</u>
2x+0y=6
2x=6
divide 2
x=3
sub back
y=-4x
y=-4(3)
y=-12
(3,-12) is answer
