Question

x+y=5 2x-3y=4 elimination method

Answer 1

Answer:

x+y=5

2x+2y=10

2x-3y=4

subtract ing,2y+3y=10-4

5y=6

y=6/5

x+y=5

x+6/5=5

x=5-6/5=(25-6)/5=19/5

Answer 2

BTS and EXO live forever

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
