Same idea as before. Multiply two segments of one chord and set equal to the product of the two segments of the other chord:
2(3x - 2) = 5x

Now you need to solve that equation for x.

First, you need to distribute the 2 on the left side.

An example of the distributive property os:
2(4x - 8) = 2*4x - 2*8 = 8x - 16
Now apply the distributive property to
2(3x - 2)

There is no equal sign inside the left side. The left side is simply
2(3x - 2)

You are very close. You are correct that there is a 4 on the right side.
Look on the left side. You have 6x on the left side and you subtracted from it 5x. What is 6x - 5x?

6x - 4 = 5x
6x - 5x = 4
