What is the value of x in the diagram?
(diagram in the following post)
a. 1/2
b. 4/21
c. 2
d. 4

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

)because it's going in order of the math sign
