\(101+\left(36-x\right)=105\)
\(\Rightarrow36-x=105-101\)
\(\Rightarrow36-x=4\)
\(\Rightarrow x=36-4\)
\(\Rightarrow x=32\)
Vậy: x = 32
101+(36-x)=105
36-x = 105-101
36-x = 4
x= 36 - 4
x = 32
Vậy x = 32
a: x-56:4=16
nên x-14=16
hay x=30
b: \(101+\left(36-4x\right)=105\)
\(\Leftrightarrow36-4x=4\)
hay x=8
Vì a: x-56:4=16
=>x-14=16
Hay:x=30
Vì b: 101+(36−4x)=105101+(36−4x)=105
⇔36−4x=4⇔36−4x=4
Hay:x=8
Vậy x={30:8}

101 + (36 - 4x) = 105
36 - 4x = 105 - 101
36 - 4x = 4
4x = 36 - 4
4x = 32
x = 32 : 4
x = 8
