Question

0.6(4х-18)-04(5-7х) 0.4(6-4х)0.5(7-3х)-1.9

Answer 1

2,4x-10,8-2+2,8x=5,2x-12,8
2,4-1,6x+3,5-1,5x-1,9=4 -3,1x

Answer 2

To simplify the given expression, let's perform the operations step by step:

1. Distribute the terms inside each parenthesis:

0.6(4x - 18) - 0.4(5 - 7x) + 0.4(6 - 4x) * 0.5(7 - 3x) - 1.9

2. Now, perform the multiplication inside each parenthesis:

0.6 * 4x - 0.6 * 18 - 0.4 * 5 + 0.4 * 7x + 0.4 * 6 - 0.4 * 4x * 0.5 * 7 + 0.4 * 4x * 0.5 * 3 - 1.9

3. Simplify the expressions further:

2.4x - 10.8 - 2 + 2.8x + 2.4 - 1.4x - 0.6 + 0.6x - 1.9

4. Now, combine like terms:

(2.4x + 2.8x - 1.4x + 0.6x) + (-10.8 - 2 + 2.4 - 0.6 - 1.9)

5. Simplify further:

(4.4x) + (-12.9)

6. Combine the remaining terms:

4.4x - 12.9

So, the simplified expression is: 4.4x - 12.9.
