Question

3/11*(1,21-4,4x)-7/9*(8,1x-3,6)

Answer 1

3/11*(121/100-22/5x)-7/9*(81/10x-18/5)=0.33-1.2x-6.3x+2.8=2.47-7.5х

Answer 2

To simplify the expression, let's start by performing the operations step by step:

1. Distribute the multiplication: 3/11 * (1.21 - 4.4x) - 7/9 * (8.1x - 3.6)

   Distributing the multiplication, we get: (3/11 * 1.21) - (3/11 * 4.4x) - (7/9 * 8.1x) + (7/9 * 3.6)

2. Multiply the constants: (0.3 - 1.2x) - (6.93x) + (2.8)

3. Combine like terms: Combine the terms that have 'x': (-1.2x - 6.93x) = -8.13x

   Combine the constant terms: (0.3 + 2.8) = 3.1

4. Final result: The simplified expression is: -8.13x + 3.1
