Answer:

The correct answer is x = -8/5 or -1.6

Explanation:

Let's simplify 2.7x -3.6(x-2) + 5.4x, this way:

2.7x -3.6(x-2) + 5.4x = 0

2.7x -3.6x + 7.2 + 5.4x = 0

27x - 36x + 54x = -72 (Multiplying by 10 and subtracting 72 at both sides)

45x = -72

x = -72/45

x = -8/5 (Dividing by 9 the numerator and the denominator)

The correct answer is x = -8/5 or -1.6
