\(819-3\left(x-5\right)=333\)
\(3\left(x-5\right)=819-333\)
\(3\left(x-5\right)=486\)
\(x-5=486:3\)
\(x-5=162\)
\(x=162+5\)
\(x=167\)
\(819-3\left(x-5\right)=333\)
\(=>819-3x+15=333\)
\(=>-3x+804=333\)
\(=>-3x=333-804\)
\(=>-3x=-471\)
\(=>x=157\)
3 ( x - 5 ) = 819 - 333
3 ( x - 5 ) = 486
x - 5 = 486 : 3
x - 5 = 162
x = 162 + 5
x = 167
