Question

3(a+b)=19 if a=6, then a+b=?

Answer 1

3(6+b)=19

18+3b=19

3b=1

b=1/3

so then a+b= 1/3+6

1/3+6=

19/3 or 6 1/3

Answer 2

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!
