3*(11-7х)-16=5
33 - 21x - 16 = 5
17 - 21x = 5
21x=17 - 5
21x = 12
x = 12:21
x = 4/7
Пожалуйста, очень нужно,и
8*(12-3х)+5=24
96 - 24x + 5 = 24
101 - 24x = 24
24x = 101 - 24
24x = 77
x = 77 : 24
x = 3 5/24
и
5/6*(1/2-х)+1/3=2/3,
5/12 - 5/6x + 1/3 = 2/3
5 - 10x + 4 = 8
9 - 10x = 8
10x = 9 - 8
10x = 1
x = 1 : 10
x = 0,1
