Question

for each value of w, determine whether it is a solution to \\(\frac{w}{3} - 1 = 9\\).\

w	is it a solution?		\
----	----	----	\
27	yes (circle)	no (circle)	\
30	yes (circle)	no (circle)	\
-3	yes (circle)	no (circle)	\
-24	yes (circle)	no (circle)

Explanation:

Step1: Test w=27

Substitute $w=27$ into $\frac{w}{3}-1$:
$\frac{27}{3}-1 = 9 - 1 = 8
eq 9$

Step2: Test w=30

Substitute $w=30$ into $\frac{w}{3}-1$:
$\frac{30}{3}-1 = 10 - 1 = 9$

Step3: Test w=-3

Substitute $w=-3$ into $\frac{w}{3}-1$:
$\frac{-3}{3}-1 = -1 - 1 = -2
eq 9$

Step4: Test w=-24

Substitute $w=-24$ into $\frac{w}{3}-1$:
$\frac{-24}{3}-1 = -8 - 1 = -9
eq 9$

Answer:

$w$	Is it a solution?
30	Yes
-3	No
-24	No
