Answer:
6
Step-by-step explanation:
First find the value for [tex]\frac{x}{3}[/tex]
[tex]-5.5+7.5=\frac{x}{3}=2=\frac{2}{1}[/tex]
Then figure out what x is like this
[tex]\frac{2}{1}=\frac{x}{3}[/tex]
Since the denominator (the bottom number) was multiplied by three we can multiply the numerator (the top number) by three so
[tex]\frac{2}{1}=\frac{6}{3}[/tex]
