2x - 1, 6 = 5, 4

The equation appears to be a typo and likely intended to be 2x - 1.6 = 5.4 or 2x - 16 = 54.

Assuming 2x - 1.6 = 5.4:

1. Add 1.6 to both sides: 2x = 5.4 + 1.6
2. Simplify: 2x = 7
3. Divide by 2: x = 3.5

Assuming 2x - 16 = 54:

1. Add 16 to both sides: 2x = 54 + 16
2. Simplify: 2x = 70
3. Divide by 2: x = 35
