d. 5
4. Which one of the following is a solution of the equation x-2y4​

Answer 1

3.

GIVEN :-

x=2 , y= 1

FIND:-

value of k

ANSWER:-

2x+3y=k

2×2 +3×1=k

4 +3 = k

7= k

THIS IS YOUR ANSWER

4.

IN THIS QUESTION IF WE PUT THE VALUE GIVEN IN THIRD QUESTION THEN ANSWER WILL BE :

=x-2y⁴

= 2 - 2(1)⁴

= 2- 2×1

=2-2

= 0

THIS IS YOUR ANSWER

PLEASE MARK ME AS BRAINLIST

Answer 2

Answer:

the answer 3 is 7 &

the answer for 4 is 0

Step-by-step explanation:

3.given x=2&y=1

2x+3y = k

(2×2)+(3×1) = k

4+3 = k

k=7

4. x-2y^4 = k

2-2(1)^4 = k

2-2(1) = k

2-2 = k

0 = k
