2.7x-3.6 (x-2) + 5.4x simplify

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

Step-by-step 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
