Answer
59
Work Step by Step
"quotient of y and 4" $\rightarrow \displaystyle \frac{y}{4}$
"1 less than the quotient of y and 4" $\rightarrow \displaystyle \frac{y}{4}-1$
"x is 1 less than the quotient of y and 4" $\rightarrow x=\displaystyle \frac{y}{4}-1$
If y=$12$, we calculate x from the last equation,
$x=\displaystyle \frac{y}{4}-1\\=\dfrac{12}{4}-1\\=3-1\\=2$
To evaluate the expression, replace x with $2$ and y with $12$:
$4(2)+3(12+5)=8+3(17)\\
=8+51\\
=59$
