Question

for each value of x, determine whether it is a solution to -27 = 3x - 9.

x	is it a solution?
2	yes	no
8	yes	no
0	yes	no

Explanation:

Step1: Substitute $x=-9$ into equation

Substitute $x=-9$ into $-17=2x-3$:
$2(-9)-3 = -18-3=-21$
Compare to left side: $-21
eq -17$

Step2: Substitute $x=2$ into equation

Substitute $x=2$ into $-17=2x-3$:
$2(2)-3 = 4-3=1$
Compare to left side: $1
eq -17$

Step3: Substitute $x=8$ into equation

Substitute $x=8$ into $-17=2x-3$:
$2(8)-3 = 16-3=13$
Compare to left side: $13
eq -17$

Step4: Substitute $x=-7$ into equation

Substitute $x=-7$ into $-17=2x-3$:
$2(-7)-3 = -14-3=-17$
Compare to left side: $-17 = -17$

Answer:

$x$	Yes	No
$2$		✕
$8$		✕
$-7$	✓
