Question

which is the solution of equation 2x+3y=7?​

Answer 1

Answer:

2x + 3 y = 7.

or, x = (7–3y)/2. …………….(1)

Putting y = 1.

x = (7- 3×1)/2 = 2. , thus ,1st solution is x = 2 , y = 1.

Putting y = -1.

x = (7+3×1)/2 = 5 , thus, 2nd solution is x = 5 , y= -1.

Putting y= 3 in eqn.(1).

x = (7–3×3)/2 = -1. thus, 3rd solution is x=-1 , y= 3.

Putting y= -3.

x = (7+3×3)/2 = 8. thus, 4th solution is x =8 , y= -3. , Answer.
