@mathstudent55 can you help?

OpenStudy (mathstudent55):

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

OpenStudy (mathstudent55):

Now you need to solve that equation for x.

OpenStudy (anonymous):

hmmm im having trouble

OpenStudy (mathstudent55):

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

OpenStudy (anonymous):

yeah so 6x = 4

OpenStudy (mathstudent55):

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)

OpenStudy (mathstudent55):

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

OpenStudy (anonymous):

oops i meant 6x - 4

OpenStudy (mathstudent55):

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

OpenStudy (anonymous):

6x - 4 = 5x

OpenStudy (mathstudent55):

Now subtract 5x from both sides.

OpenStudy (anonymous):

is the final answer -1x = 4?

OpenStudy (anonymous):

i mean -4

OpenStudy (anonymous):

it cant be

OpenStudy (anonymous):

1x - 4

OpenStudy (mathstudent55):

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?

OpenStudy (mathstudent55):

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

OpenStudy (anonymous):

is it 1x?

OpenStudy (anonymous):

so 1x = 4

OpenStudy (anonymous):

so is 3 the final answer?

OpenStudy (anonymous):

no because 5 + 3 is not 9

OpenStudy (anonymous):

ughh im getting frustrated lol

OpenStudy (mathstudent55):

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

OpenStudy (anonymous):

lol i completely missed that

OpenStudy (mathstudent55):

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

OpenStudy (anonymous):

yeah i forgot about that. Thanks!
