Hello!
In a really simple way, 3 times our answer is 19. We can just divide to find it.
19/3= 6 1/3
Anyway, it might be nice to solve the equation for b. If a=6, then b has to be 1/3, but let's check.
18+3b=19
3b=1
b=1/3
Therefore, a+b= 6 1/3
I hope this helps!

Answer:
X=5
Step-by-step explanation:
f(1)= -1^2+4(1)+12=15
f(2)= -2^2+4(2)+12=16
f(3)= -3^2+4(3)+12=15
f(4)= -4^2+4(4)+12=12
f(5)= -5^2+4(5)+12=7
g(1)=1+2=3
g(2)=2+2=4
g(3)=3+2=5
g(4)=4+2=6
g(5)=5+2=7
so g(5)=f(5)= X=5
