Question

give geometric representation of 2x+9=0 as an equation a) in one variable b) in two variables

Answer 1

Step-by-step explanation:

Given that is a linear equation in one variable

the sum of 9 and twice of x is equal to 0

2x+9=0

=>2x=-9

=>x=-9/2

Answer 2

$The \: sum \: of \: 9 \: and \: twice \: of \:x= \: 0$

$2x + 9 = 0 \\ \\ 2x = - 9 \\ \\ x = \frac{ - 9}{2} \\ = - 4.5$
