Question

Which of the following equations have the same solution? Solve all three equations separately, and explain each step.  I. 3x + 2 = 5x – 6 II. 2x – 2 = 8 III. the quantity of x plus 1, divided by 5 equals the quantity of 2x minus 2, divided by 6

ranga · Answer

To solve 3x + 2 = 5x – 6, isolate x.
subtract 3x from both sides.
add 6 to both sides.
solve for x.

so i dont understand how to do number two it says they all have the same solution but i came up with x=5 why?

ranga · Answer

It does not say they all have the same solution.  It is asking you to solve all three equations separately and then asking you which ones have the same solution.  x = 5 is correct for problem 2.  What did you get for problems 1 and 3?
