Question

Solve: (x-2)/3 - (x-2)/5 = 2
I keep getting 13 when the answer is 7.

Answer 1

can you show your steps ? i'll help you spot the error :)

Answer 2

(5x+10)/15 - (3x-6)/15 = 2
(2x+4)/15 = 2
I multiplied both sides by 15 to get rid of the denominator
2x+4=30
2x=26
x=13

Answer 3

shouldn't that be 5x-10 instead of 5x+10 ???
and actually , the correct answer is 17, not 7

Answer 4

5(x-2) = 5x -10

Answer 5

oh, its x+2 in the question...

Answer 6

so, your mistake actually is
(5x+10)/15 - (3x-6)/15

= (5x+10 - 3x -(-6)) /15

Answer 7

5x+10 -3x +6
= 2x +16

you got 2x+4 instead

Answer 8

I just got (5x+10 - 3x -(-6)) /15 incorrect.
So it would be 2x+16 instead of 2x+4, which would end up giving me the 7 I need.
