The answer to the question above, the line of your triangle shows that it's divided proportionally.
So, the equation will look like this,
9( 3x + 2) = 12(4x - 2)
Then simplify the equation,
27x + 18 = 48x - 24
After that, transpose 48x to the left and 18 to the right.
27x+42 = 48x
Divide both sides by 21x
42 = 21x
21 21
so the answer will be 2
