Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.
This is the answer the x=3 and the y=2
if x is 8 then 12(8) + 12
12 times 8 is 96
96 + 12=108
the answer is 108
You have two people answer and whoever answer you think is better you can mark them as brainliest
