​

Answer 1

Question :-

Find the value of k, if x =2,y=1 is a solution of the equation 2x +3y = k.

Answer :-

• k = 7

Step by step explanation :-

How to solve :

• Here we have a linear equation and we also given that the value of x and y, then it's very easy to solve we can substitute the value of x and y in the equation and find k.

Substituting x = 2 and y = 1 in equation,

➦ 2x + 3y = k

➦ 2(2) + 3(1) = k

➦ 4 + 3 = k

➦ k = 7 $\:$
