\(100-7\left(x-5\right)=65\)

\(\Leftrightarrow7\left(x-5\right)=35\)

\(\Leftrightarrow x-5=5\)

\(\Leftrightarrow x=10\)

Vậy x = 10

\(219-7\left(x+1\right)=100\)

\(\Leftrightarrow7\left(x+1\right)=119\)

\(\Leftrightarrow x+1=17\)

\(\Leftrightarrow x=16\)

Vậy x = 16

\(2x+5x=2\cdot5^2-1\)

\(7x=2\cdot25-1\)

\(7x=50-1\)

\(7x=49\)

\(x=7\)

Vậy x = 7

\(2448:\left[119-\left(x-6\right)\right]=24\)

\(\Leftrightarrow119-\left(x-6\right)=102\)

\(\Leftrightarrow x-6=17\)

\(\Leftrightarrow x=23\)

Vậy x = 23

\(\left(6^{15}\cdot6^2\right):6^4=6^{15+2}:6^4=6^{17}:6^4=6^{17-4}=6^{13}\)
