Решите уравнения пожалуйста! -(4-х)-4(х-5)=5(1-х) 4,5(х-2)-3(8+2х)=4х
- 4 + x - 4x + 20 = 5 - 5x - 3x + 16 = 5 - 5x - 3x + 5x = 5 - 16 2x = - 11 x = - 5,5 4,5x - 9 - 24 - 6x = 4x - 1,5x - 33 = 4x - 1,5x - 4x = 33 - 5,5x = 33 5,5x = - 33 x = - 6
1) -(4-x)-4(x-5)=5(1-x) -4+x-4x+20=5-5x 16-3x=5-5x -3x+5x=5-16 2x=-11, x=-11/2, x=-5,5 2)4,5(x-2)-3(8+2x)=4x 4,5x-9-24-6x=4x -1,5x-33=4x -1,5x-4x=33 -5,5x=33 x=-33/(5,5), x=-6
