6

#### Explanation:

I'm going to use $Y$ in place of the unknown variable.

$7 + 7 \times Y - 5 = 79$

First, you will add the two sevens at the beginning together..

$14 \times Y - 5 = 79$

Then, you will add five to the other side of the equation.

$14 \times Y = 84$

Finally, you will divide both sides of the equation to get...

$Y = 6$
