Answer:
Given: [tex]15+6(y-2)=21[/tex]
Distributive Property tells us that we multiply each term inside the parentheses with the term outside of the parentheses.
[tex]a\cdot(b-c) =a\cdot b -a\cdot c[/tex]
Using distributive property on expression 6(y-2) to solve the further expression as:
[tex]15+6\cdot y - 6\cdot 2=21[/tex]
Simplify:
[tex]15+6y-12 =21[/tex]
Subtract the number 12 from 15 we get 3;
therefore, the expression become:
[tex]6y+3=21[/tex]
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;
[tex]6y+3-3=21-3[/tex]
Simplify:
[tex]6y=18[/tex]
Now, divide by 6 on both the sides we get;
[tex]\frac{6y}{6}= \frac{18}{6}[/tex]
On simplify we get;
y =3 Hence Proved!
Answer:
y =3 should be the correct answer
