\(100-7\cdot\left(x-5\right)=58\)
\(7\cdot\left(x-5\right)=100-58\)
\(7\cdot\left(x-5\right)=42\)
\(x-5=\frac{42}{7}=6\)
\(\Rightarrow x=6+5\)
\(\Rightarrow x=11\)
\(100-7.\left(x-5\right)=58\)
\(7.\left(x-5\right)=100-58\)
\(7.\left(x-5\right)=42\)
\(x-5=42:7\)
\(x-5=6\)
\(x=5+6\)
\(x=11\)
Vậy \(x=11\)
100-7.(x-5)=58
7.(x-5)=100-58
7.(x-5)=42
x-5=42:7
x-5=6
x =6+5
vậy=11
