a: =>2x-5=-11
=>2x=-6
hay x=-3
b: =>2(4-3x)=14
=>4-3x=7
=>3x=-3
hay x=-1
c: =>3x-2=-8
=>3x=-6
hay x=-2

a. 9 - 35 = (17 - x) - (35 + 17)
=> -26 = 17 - x - 52
=> x = 17 - 52 + 26
=> x = -9
b. -7 - (12 + x) = -(-14 + 3) - (2x - 7)
=> -7 - 12 - x = - (-11) - 2x + 7
=> -19 - x = 11 + 7 - 2x
=> 2x - x = 18 + 19
=> x = 37
\(\text{ 3*x+17=12}\)
\(3.x=12-17\)
\(3.x=-5\)
\(\Rightarrow x=\frac{-5}{3}\)
3.x + 17 = 12
3.x = 12 - 17
3.x = 12 + ( -17 )
3.x = -5
x = -5 : 3
x = -5/3
Vậy x = -5/3
