Question

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

Answer 1

Answer:

-12 is your answer

Step-by-step explanation:

3*-2+2*-2=k,-6-4= -10

Answer 2

Answer:-

The Required Value Of k is -8.

Explanation:-

Given:-

• An equation 3x + 2y = k.
• The Solutions of the equation are x = -2 and y = -1.

To Find:-

• The Value of k.

Now,

• Since we have already given the values of x and y which are -2 and -1 respectively.

By substituting the Values of x and y in given equation we get:-

↦ 3x + 2y = k.

↦ k = 3x + 2y.

↦ k = 3(-2) + 2(-1) {By Putting Values}.

↦ k = (-6) + (-2).

↦ k = -6 - 2.

↦ k = -8.

Therefore The Required Value Of k is -8.

More To Know:-

• The equation having two variables (i.e. unknown values) is called an equation with two variables.

• The pair of equations in two variables can be mainly solved by three methods.

• These methods are:- Cross - Multiplication Method, Elimination Method and Substitution method.
