the answer of the question is tens
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!

Solve the above equations,

First term is -13.
