Answer 1

Answer:

1. $\huge \sf \underline{ \ given\: : }$

$\sf \: 2x + 9 = 0$

$\huge \sf \underline{ \ to \: find\: : }$

$\sf \: linear \: equation \: in \: one \: variable$

$\sf \: linear \: equation \: in \: two \: variable$

$\huge \sf \underline{ \ solution \: : }$

$\sf \: (i)linear \: equation \: in \: one \: variable$

$\sf \to \: 2x + 5 = 0$

$\sf \to2x = - 5$

$\sf \to \: x = \frac{ - 5}{2}$

$\red {\sf {\to \: x = - 2.5}}$

$\purple{\fbox{( - 2.5,5)}}$

$\sf \:(ii) linear \: equation \: in \: two \: variable$

$\sf \bull \: let \: the \: value \: of \: (x)\: be \: (0)$

$\sf \to2(0) + 5 = 0$

$\sf \to0 + 5 = 0$

$\red{ \sf \to(0,- 5)}$

$\purple{\fbox{( 0,-5)}}$
