Question 2 of 10

Mathematics

Archy [21]3 years ago

Answer:

3y-6=18\\\\3y=24

The value of "y" is: y=8

Step-by-step explanation:

Given the following equation:

3(y-2) = 18

1. You must apply the Distributive property on the left side of the equation (This is: a(b\±c)=ab\±ac). Then:

(3)(y)+(3)(-2) = 18\\\\3y-6=18

2. Now you need to apply the Addition Property of Equality. Remember that this states that:

If\ a=b,\ then\ a+c=b+c

So, adding 6 to both sides of the equation, you get:

3y-6+(6)=18+(6)\\\\3y=24

3. Finally, you can apply the Division Property of Equality, which states that:

If\ a=b,\ then\ \frac{a}{c}=\frac{b}{c}

So, dividing both sides of the equation by 3, you get:

\frac{3y}{3}=\frac{24}{3}\\\\y=8
