Пошаговое объяснение:
5x-x-x/2 = 2/9-2/6
7/2x = -1/9
x = -1/9*2/7
x = -2/63
5+2x/3=x-3/5+x+5/2
2x-2/3x = 5+3/5-5/2
4/3x = 31/10
x = 31/10*3/4
x = 93/10
3(x+1)/8+2(5x)/3=16-13x/12 ×24
9(x+1)+16*5x = 384-26x
9x+9+80x = 384-26x
89x+26x = 384-9
115x = 375
x = 375/115 = 75/23 = 3 6/23
5(7-2x)/3-4x-2/9=x-19/2 ×18
30(7-2x)-72x-4 = 18x-171
210-60x-72x-4 = 18x-171
18x+60x+72x = 210-4+171
150x = 377
x = 377/150 = 2 77/150
