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
