$let \: \: \: 2x + y = 5 -----(1) \\ \\ and \: 3x - y = 5 \: -----(2) \\ \\ adding \: equations \: (1) \: and \: (2) \: we \: get \: \\ 5x = 10 \\ x = 10 \\ \\ now \: putting \: x = (2) \: equation \: (1) \: we \: get \: \\ \\ 4 + y = 5 \\ \\ y = 1$

Answer 2

Answer:

x=2

y=1

Step-by-step explanation:

let be,

2x + y = 5........1

3x - y = 5.........2

when the coefficient of one of the variable is same that time we can add or subtract ...

coefficient of y is same so we haven't need to do same the coefficient of one of them ( coefficient of x or y)

then...

add 1 and 2

2x + y = 5

3x - y = 5

_________

5x = 10

x = 10 ÷ 5

x = 2

then x = 2 out in 1

2x + y = 5

2(2) + y = 5

4 + y = 5

y = 5-4

y = 1

therefore

x=2

y=1
