Thread: Solving Linear Equations

Solve:



Multiplying by 12 you get:

9 - x + 1 = 8 - 2(x - 1)
10 - x = 8 - 2x + 2
10 - x = 10 - 2x
10 + x = 10

Therefore x = 0

The answer says x = 2, I don't know where I went wrong.

Mr F says: 9 - (x + 1) = 8 - 2(x - 1)

9 - x + 1 = 8 - 2(x - 1) Mr F says: Should be 9 - x - 1 = 8 - 2(x - 1)
