In which step did Victor make a mistake?

Step 3

Step-by-step explanation:

-2/3x - 3/4x = 5/6

-8/12x - 9/12x = 5/6

-17/12x = 5/6

(-12/17) (-17/12)x = (5/6) (-12/17)

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
