Answer 2

Here's the formula

Answer 3

So set it up

9 * (9+12) = 3 * (3+x)

Can you solve for x?

Answer 4

Uh second

Answer 5

x = 11?

Answer 6

Not quite

what is 9+12 = ?

and on the other side of the equal sign
can you distribute the 3 into the parenthesis?

\( a(b+c) = ab + ac\)

Answer 7

21

Answer 8

Good, so then you have

9 * 21 = 3(x + 3)

What is 9 * 21 = ?

Answer 9

189

Answer 10

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

Answer 11

60?

Answer 12

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