Question

If (2, 3) is a solution of linear equation 2x +3y = k then the value of k is.​

Answer 1

$\huge\underbrace\mathcal\pink{here \: is \: your \: answer}$

Given : 2x + 3y = k

From the coordinate, (2, 3)

It is clear that,

x = 2 and

y = 3

Putting these values in given equation,

2x + 3y = k

2(2) + 3(3) = k

4 + 9 = k

k = 13

Hope this helps ✌✌✌
