Given: 15+6(y−2)=21 prove: y = 3 drag and drop the reasons into the boxes to correctly complete the proof. statement reason 15+6(y−2)=21 given 15+6y−12=21 6y + 3 = 21 6y = 18 y = 3

Given:  

Distributive Property tells us that we multiply each term inside the parentheses with the term outside of the parentheses.

Using distributive property on expression 6(y-2) to solve the further expression as:

Simplify:

Subtract the number 12 from 15 we get 3;

therefore, the expression become:

Subtraction property of equality tells us that subtract the same number from both sides of an equation.

Now, subtract 3 from both the sides we get;

Simplify:

Now, divide by 6 on both the sides we get;

On simplify we get;

y =3           Hence Proved!

answer: b
