Question

for each value of x, determine whether it is a solution to $5x - 9 = -44$.

	is it a solution?
0	$\circ$	$\circ$
-7	$\circ$	$\circ$
10	$\circ$	$\circ$
4	$\circ$	$\circ$

Explanation:

Step1: Test x=0 in equation

Substitute $x=0$ into $5x-9=-44$:
$5(0)-9 = 0-9 = -9
eq -44$

Step2: Test x=-7 in equation

Substitute $x=-7$ into $5x-9=-44$:
$5(-7)-9 = -35-9 = -44 = -44$

Step3: Test x=10 in equation

Substitute $x=10$ into $5x-9=-44$:
$5(10)-9 = 50-9 = 41
eq -44$

Step4: Test x=4 in equation

Substitute $x=4$ into $5x-9=-44$:
$5(4)-9 = 20-9 = 11
eq -44$

Answer:

• $x=0$: No
• $x=-7$: Yes
• $x=10$: No
• $x=4$: No
