This is similar to Problem 1 from your Section 2.3 worksheet.

For each sentence, choose the equation that best represents the situation.

1) $x$ is $47$ less than $y$:
$x=y-47$
$x=47-y$
$y=x-47$
$y=47-x$

2) $y$ is $87$% of $x$:
$x=0.87 y$
$y=87-x$
$y=0.87 x$
$y=87 x$

3) $y$ is half of $9 x + 1$:
$9 x + 1 = \frac{1}{2}y$
$y=\frac{1}{2}(9 x + 1)$
$y=\frac{1}{2}9 x + 1$
$\frac{1}{2}y=\frac{1}{2}(9 x + 1)$

4) The total of $3$ less than $y$ and $z$ less than $6$ is $15$:
$(y-3)+(6-z)=15$
$(3-y)+(6-z)=15$
$(y-3)+(z-6)=15$
$(3-y)+(z-6)=15$
