    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.

    yeah so 6x = 4

    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)

    Good, now that is equal to 5x, so write that.

    6x - 4 = 5x

    Now subtract 5x from both sides.

    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

    1x = 4 means x = 4. x = 4 is the final answer

    1x is the same as x. 1b is the same as b. etc.
