Question

solve simultaneous equations

(2x+y=5,2x-y=5)

​

Answer 1

Answer:

Answer

Given

2x+y=5

y=5−2x.

3x−y=5

substitute value of y from (1) in the above equation, we get

3x−(5−2x)=5

3x−5+2x=5

3x+2x=5+5

5x=10

x=

5

10

x=2

Putting value of x in (1) ,we get

y=5−2x

y=5−2×2

y=5−4

y=1

Therefore, x=2 and y=1

Answer 2

4x=10

x=5/2

2y=10

y=5

i think my answer is correct
