<span>-3x + 2y = 2 eq (1)
7x - 3y = 7 eq (2)
Mutiply eq (1) by 3 and eq (2) by 2:
-9x + 6y = 6
14x - 6y = 14
Add th two new equations:
-9x + 14x = 6 + 14
=> 5x = 20
=> x = 20/5
=> x = 4
Now from eq (1)
-3(4) + 2y = 2
=> 2y = 2 + 12
=> 2y = 14
=> y = 14 / 2
=> y = 7
So the ordered pair is (4,7)

Answer:
f(-5)= 90, g(7)= -3x+4
Step-by-step explanation:
First Solve f(x)
f(x)= 3×^2-3x
Plug in -5 to the x
3(5)^2-3(-5)
f(x)= 90
Then Solve g(x)
g(x)=-3x+4
Plug in the 7 in the x
g(x)=-3x+4
g(x)=17
