The first one would be correct!
You can solve simultaneously to find the intersection of the lines. Or use the substitution method,
I used the substitution method where I made X the subject in the first method so I got X = -2 +y
use this x to replace it in the second equation
y= 2(-2 + y ) +10
therfore y = 2
to find x coordinate, substitute y in any equation to get x = - 4
so the points of intersection is (-4, 2)
Hope this helped! :)

Answer: 9^-8
Step-by-step explanation:
To get single positive exponent,
9^-5 / 9^3
Since the exponent is same
So we can solve the coefficient like this
9^-5-3
So
9^-8
