Question

26. Find the value of k if
x=2and y=-1 is a solution of the
equation 2x+3y=k *
1 or 7 or 3​

Answer 1

Answer:

2x+3y=k

substituting the given values

2(2)+3(-1)=k

4+(-3)=k

4-3=1=k

Answer 2

Given:-

• 2x+3y = k

• x =2 y = -1

To Find :-

• To Find the Value of k in the equation.

Solution :-

We are given with an equation 2x+3y = k

In this case x = 2 and y = -1 is already given so by giving x and y let us solve the equation to obtain the value of k.

• 2x+3y = k is the quation given so Substitute the value of x and y

• 2*2+3*-1 = k

• 4+(-3) = k

A positive number and a Negative number so, just take the number difference and give sugn of the big number.

here 4 is the biggest number so give the sign of 4 = +

• 4+(-3) = 1

• so, the value of k = 1
