-3y-2=7 what is the value of y
2 answers:
Answer:
y = -3
Step-by-step explanation:
Add 2 to each side to isolate the -3y. Doing this leaves you with -3y=9. You then divide each side leaving you with y = -3
Answer:
The equation has one solution at which y = -3.
Step-by-step explanation:
To find the value of y, we need to isolate it from the rest of the equation.
- Add 2 to both sides of the equation.
- Divide by -3 on both sides of the equation.
- Simplify the equation if necessary.

We can check to make sure that y = -3 by substitution.

Because we got a true statement, we can determine that y = -3.
