Answer:
y = -10
Step-by-step explanation:
-3(y+5)=15
Divide each side by -3
-3/-3 (y+5)=15/-3
y+5 = -5
Subtract 5 from each side
y+5-5=-5-5
y = -10
Answer: [tex]y=-10[/tex]
Simplify both sides of the equation
[tex](-3)(y)+(-3)(5)=15(Distribute)\\-3y+-15=15[/tex]
Add 15 to both sides
[tex]-3y-15+15=15+15\\-3y=30[/tex]
Divide both sides by -3
[tex]\frac{-3y}{-3} =\frac{30}{-3} \\x=-10[/tex]
