Answer:
[tex]-\frac{32}{3}[/tex] or -10.666666666666 or -10 2/3.
Step-by-step explanation:
The question is asking what Y value makes them equal to each other. Thankfully you know that your primary (and only) goal is to isolate the y value and get it's numerical value.
First let's simplify the equation.
-6y-90=3y+6
Now lets do the PEMDAS operations to isolate Y and get it's numerical value.
-6y-90=3y+6
-6y-90-6=3y+6-6
-6y-96=3y
-96=9y
[tex]-\frac{32}{3}[/tex] = y
