Answer 2

$\bold \red \star \: \underline{Given:-} \begin{cases} \sf{x = 3.} \\ \sf{y = 5.} \\ \sf{z = 4.} \end{cases}$

$\rule{200}2$

$\bold \red \star \: \large\underline{Solution:-}$

$\tt{We \: have \: \red{equation}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 5x + 3y - 6z$

$\tt{Putting \: the \: value \: \red{given, }}$

$\rule{200}2$

$\\ \\ = 5(3) + 3(5) - 6(4). \\ \\ = 15 + 15 - 24. \\ \\ = 30 - 24. \\ \\ = 6$

$\tt{Therefore, \: the \: Value \: of \: equation \: be \: \red{ 6}.}$
