Answer 1

Answer:

❤️❤️❤️❤️❤️❤️Hey mate ....

your answer is..

====>> In the example

x + y = 4 ......................(1)

2x - 5y = 1 .....................(2)

Multiplying by 5 equation (1) we get,

5(x + y = 4)

5x + 5y = 20 .................(3)

Adding equation (2) and (3) we get,

2x - 5y = 1

5x + 5y = 20

---------------------

7x = 21

x = 21/7

x = 3

x = 3 taking equation (2) we get,

2x - 5y = 1

2(3) - 5y = 1

6 -5y =

-5y = 1 - 6

-5y = -5

y = -5/-5

y = 1

Therefore, x = 3 and y = 1 are the solution of the given equation.

Thanks..
