Question 627732: Hello My name is Aj and this is my problem:
I must "Solve for given variable" (I presume they want me to solve for "x")
(3x +4)/(x -2) = 5/6 The answer is " x = -(34/13) "
THINGS I HAVE TRIED
Step 1 : (3x +4)/(x -2) = 5/6
vvvvvvvvvvvv
2x -2 = 5/6
(I divided the two set of numbers because I didn't know any other way of getting rid of the second variable.)
Step 2 : 2x -2 = 5/6
(add +2 to both sides to get rid of the "-2")
vvvvv vvv
2x = 17/6

Step 3 : (2x)/2 = (17/6)/2
vvvvvv vvvvvvvv
x = ?
(I don't even know how to go about finishing this. but whatever this answer would end up being, im pretty sure its not " x = -(34/13)" )
My question is,"What am I doing wrong, and How do I correctly solve for " x ". "
Thank you for you time and your assistance,
AJ.

%283x+%2B4%29%2F%28x+-2%29+=+5%2F6 Start with the given equation


6%283x+%2B4%29+=+5%28x+-2%29 Cross multiply


18x%2B24=5x-10 Distribute.


18x=5x-10-24 Subtract 24 from both sides.


18x-5x=-10-24 Subtract 5x from both sides.


13x=-10-24 Combine like terms on the left side.


13x=-34 Combine like terms on the right side.


x=%28-34%29%2F%2813%29 Divide both sides by 13 to isolate x.


----------------------------------------------------------------------

Answer:

So the solution is x=-34%2F13

So your answer is correct. However, there are a few issues in your steps (eg: you lost a negative sign somewhere, not sure where).

In general . And even so, how did you manage to come up with ?

What you need to do first is cross-multiply. In general, the process is the numerator on one side of the equals sign times the denominator on the other side is equal to the denominator on the first side times the numerator on the other side, thus:



To specifics:



Applying the cross-multiply process:



Distribute to remove parentheses:



I'll let you take it from here.
