Match each expression with an equivalent expression.
Marysya12 [62]

Answer:

6x-4y →  4.  2(3x-2y)

6-4x →    3.  2(3-2x)

6x-4x →  1. 2x

6x-4 →   2. 2(3x-2)

Step-by-step explanation:

You need to:

 Factor out 2 from 6x-4y,  then you get the equivalent expression:

=2(3x-2y) this matches with OPTION 4

Factor out 2 from 6-4y, then you get the equivalent expression:

=2(3-2x) this matches with OPTION 3

Make the subtraction for 6x-4x,  then you get the equivalent expression:

=2x this matches with OPTION 1

Factor out 2 from 6x-4,  then you get the equivalent expression:

=2(3x-2) this matches with OPTION 2

Hey there!

First, let's multiply each side of the equation by 3 to get rid of the fraction \frac{2}{3}.

9 + 2x = \frac{6}{5}

Next we can multiply each side of the equation by 5 to get rid of the fraction \frac{6}{5}.

45 + 10x = 6

There's your answer!

Hope this helps!
