Question

Co 4. Which of the following is a solution of the equation x + 2y = 7 ? (a) x = 3, y = - 5 (b) x = 3, y = 5 { x = 0, y = 7 (d) x = 3, y = 2​

Answer 1

Step-by-step explanation:

x+2y= 7

step 1

put y = 2

put y = 2

put y = 2 x+2(2) = 7

put y = 2 x+2(2) = 7x+(4) = 7

put y = 2 x+2(2) = 7x+(4) = 7x = 7 - 4

put y = 2 x+2(2) = 7x+(4) = 7x = 7 - 4x = 3

put y = 2 x+2(2) = 7x+(4) = 7x = 7 - 4x = 3

put y = 2 x+2(2) = 7x+(4) = 7x = 7 - 4x = 3 option (d) x = 3, y = 2is the correct answer
