Question

If 8f + 7 - 2f = 16, what
is the value of 12 f + 1?

I need help

Answer 1

Distribute and simplify to get 6f=9. This means f=1.5 plug 1.5 in for 12f and get 18. 18+1=19

Answer 2

$8f+7-2f=16\\6f=16-7\\6f=9\\f=\frac{9}{6}$

We know f, now we want the 12f+1

Therefore, Substitute f = 9/6 in 12f+1

$12(\frac{9}{6})+1\\ = 2*9+1\\=18+1\\=19$

If you are wondering where 2*9 comes from, it comes from the 12(9/6) and 12 is divided by 6 then we get 2 and multiply the 9 as we get 2*9.
