Answer:

$\huge{ \underbrace{ \color{red}{Answer}}} \\ \\ x = 4 \\ y = - 3 \\ \\ -2x + 3y = k \\ -2(4) + 3( - 3) = k \\ -8 + ( - 9) = k \\ -8 - 9 = k \\ \large {\boxed{ \underline{ \underline{- 17}} = k}}$

vidhitrivedi380: its wrong

vidhitrivedi380: can u explain more..

harshitha926594: "If (4,-3) is a solution of the equation : -2x + 3y = k" ▶It means, they have solved the equation and found the values of x and y. They have given the values of x and y in bracket. They are asking us to find the value of k. We should find the value of k by adding the values of x and y in the solution.

harshitha926594: if any doubt, plz ask

vidhitrivedi380: clear

vidhitrivedi380: now doubt
