Here's the formula

AZ:

So set it up 9 * (9+12) = 3 * (3+x) Can you solve for x?

Allison:

Uh second

Allison:

x = 11?

AZ:

Not quite what is 9+12 = ? and on the other side of the equal sign can you distribute the 3 into the parenthesis? \( a(b+c) = ab + ac\)

Allison:

21

AZ:

Good, so then you have 9 * 21 = 3(x + 3) What is 9 * 21 = ?

Allison:

189

AZ:

so we have 189 = 3(x+3) divide 3 on both sides so we can slowly get x all by itself 189 / 3 = x + 3 and then subtract 3 on both sides

Allison:

60?

AZ:

There you go!! That's your final answer :)
