Kim is solving the following linear equation.

11+3x-7=6+5-3x
Her final two steps are:

4+3x=3x+5
4=5

Select the statement that correctly interprets Kim's solution.
The solution is x = 0.
The solution is the ordered pair (4, 5).
There is no solution since 4 = 5 is a false statement.
There are infinitely many solutions since 4 = 5 is a false statement

Is it possible to say that 4 is the same thing as 5?

anonymous · Answer

11 + 3 x - 7 = 6 + 5 - 3 x
x = 7/6

calculusxy · Answer

11 + 3x - 7 = 6 + 5 - 3x
4 + 3x = 11 - 3x 
4 + 6x = 11
6x = 7
x = 7/6

@robtobey says the correct solution. It doesn't make sense how Kim would get 4 = 5 as the solution to this linear equation.
