Answer 1

Answer:

2x+3y=k

x=2

y=1

2 (2)+3 (1)=k

4+3=k

7=k

k=7

Answer 2

GivEn:

• The given equation is 2x+3y = k

To Find:

• The Values of k ?

Solution:

According to the question, x = 2 and y = 1.

Now,

Substituting the values of x and y in the equation2x+3y = k

We get;

⟹ (2×2)+(3×1) = k

⟹ 4+3 = k

⟹ 7 = k

⟹ ${\boxed{\sf\bf\pink{ k = 7}}}$

Hence,

The value of k, if x = 2, y = 1 is a solution of the equation 2x+3y = k is 7.
