\(30\left(x+2\right)-6\left(x+5\right)-24x=100\)
\(30x+60-6x-30-24x=100\)
\(0x+30=100\)
\(0x=70\)
\(\Rightarrow x\in\varnothing\)
30(x + 2 ) - 6(x+5) - 24x = 100
30.x+30.2-6.x-(-5.6) -24x = 100
30 x + 60-6.x + 30 - 24x = 100
( 30x - 6x - 24x ) + 60 + 30 = 100
x( 30-6-24 ) + 90 = 100
x.0 = 100-90
x.0 = 10 ( vô lý )
Vậy x = \(\varnothing\)
