\(4-\left(x-3\right)=7^2-1^{10}\\ =>4-x+3=49-1\\ =>7-x=48\\ =>x=7-48\\ =>x=-41\)
\(4-\left(x-3\right)=7^2-1^{10}\)
\(4-\left(x-3\right)=49-1\)
\(4-\left(x-3\right)=48\)
\(-\left(x-3\right)=48-4\)
\(-\left(x-3\right)=44\)
\(x-3=-44\)
\(x=-44+3\)
\(x=-41.\)
\(Vậy...\)
\(\Leftrightarrow4-\left(x-3\right)=49-1\)
\(\Leftrightarrow4-\left(x-3\right)=48\)
\(\Leftrightarrow x-3=4-48\)
\(\Leftrightarrow x-3=-44\)
\(\Leftrightarrow x=-44+3\Leftrightarrow x=-41\)
