Question

find four solution of2x+y=7​

Answer 1

Answer:

2x + y = 7

Put x = 1

2(1) + y = 7

y = 7-2

y = 5

Put x = 2

2(2) + y =7

4 + y =7

y = 7 - 4

y = 3

Put x = - 1

2(-1) + y = 7

-2 + y =7

y = 7 + 2

y = 9

For next solution you can the value of x.

Here (x,y) = (1,5) ; (2,3) ; (-1,9)..

Answer 2

Step-by-step explanation:

2x+y=7

➡️(transpose 2 from LHS to RHS)

➡️x+y=7-2

➡️xy=5

note:-

*transpose means to take one value from 1 place 2 another

*in maths transpose is used to take the value from one plave two other when there is (=)sign in the expresion that is equation

remember= when u transpose sign changes

*(-)=(+)

*(+)=(-)

*(×)=(÷)

*(÷)=(×)
