Question

4x+5y=13
2x+y=5
by elimination method ​

Answer 1

Answer:

answer in elimination method.

Step-by-step explanation:

4x+5y =13...(1)

2x+y=5...(2)

multiply (1)eq by 2 and (2) by 4

which is

8x +10y = 26…....(3)

8x + 4y = 20…......(4)

now subtract (4) from (3)

6y=6

y=1

now put y=1 in any eq..

than x= 2

Answer 2

4x+5y=13.....(i)

2x+y=5.........(ii)

let multiply equation (ii) with 5

=10x+5y=25...(iii)

Now subtract (iii) from one:

10x+5y=25

4x +5y=13

-. -. -

6x. =12

X=12/6

X = 2

Now put the value of X in equation (ii)

2×2+y=5

4+y=5

y=5-4

y=1
