Question

пожалуйста!!! помогите ​

Answer 1

Объяснение:

1. 5/12x + 4x/3 = 15+48x²/36x

2. 3-x/6 - 5/4x = 4x(3-x)-30/24x = 12x-4x²-30/24x

3. 5x/18x+6 + x/3x+1 = 5x/6(3x+1) + x/3x+1 = 5x+6x/6(3x+1) = 11x/18x+6

4. 3b/1-3b - 5b/6b-2 = 3b/1-3b + 5b/1-3b = 3b+5b/1-3b = 8b/1-3b

5. x+5/x²-16 + 2x/x+4 = x+5/(x-4)(x+4) + 2x/x+4 = x+5+2x(x-4)/(x-4)(x+4) = x+5+2x²-8x/(x-4)(x+4) = 5+2x²-7x/(x-4)(x+4)
