Question

x + y = 5 and 2x - 3y = 4.
find x and y​

Answer 1

Answer:

x + y = 5 ( equation 1 )

2x - 3y = 4 ( equation 2 )

Now,

multiplying (eq.1) by 2 and subtracting (eq.2) from ( eq.1 )

(2x + 2y = 10) - (2x - 3y = 4 )

=> 2x + 2y - 2x + 3y = 6

=> 5y = 6

=> y = 6/5

Putting the value of y in ( eq.1 )

=> x+ y = 5

=> x + 6/5 = 5

=> x = 5 - 6/5

=> x = 19/5

Step-by-step explanation:

Answer 2

Answer:

x = 19/5

y = 6/ 5

Step-by-step explanation:

The following image explains the steps

Using simultaneous equations the value of x comes out to be 19/5 and the value of y comes out to be 6/5 .
