Question

Find 5 solutions of 2x+3y=9

Answer 1

Answer:

we can use trial and error method for this question

2x+3y=9

first put the equation in y in terms of x

that is y= 9-2x/3

let us see what numbers will come in place of x and y

let us replace with 0 for x first

==> y= 9- 2(0)/3

==> y= 9-0/3

==> y=3

so one solution is (0,3) - we put x value first then y , in the form(x,y)

hope this helps you

Answer 2

$\: \huge\bf\underline \red{\underline{Answer}}$

we will use Trial and Error Method

$2x + 3y = 9$

$1) \: let \: x = 0$

$for \: 2x + 3y = 9$

$= > 2 \times 0 + 3y = 9$

$= > y = \frac{9}{ 3}$

$= > y = 3$

$2) \: let \: y = 0$

$for \: 2x + 3y = 9$

$= > 2x \times 0 = 9$

$= > x = \frac{9}{2}$

$3) \: let \: x = 1$

$for \: 2x + 3y = 9$

$2 + 3y = 9$

$= > 3y = 7$

$= > y = \frac{7}{3}$

$4) \: let \: y = 1$

$for \: 2x + 3y = 9$

$= > 2x + 3 = 9$

$= > 2x = 6$

$= > x = \frac{6}{2} = 3$

$5) \: let \: x = - 3$

$for \: 2x + 3y = 9$

$= > - 6 + 3y = 9$

$= > 3y = 15$

$= > y = \frac{15}{3} = 5$
