Question

solve the following simuttaners equation. 2x+y=5 ; 3x-y=5 .​

Answer 1

Answer:

let x = 1

2×1+y=5

2+y=5

y=5-2

y=3

let x = 2

3×2-y=5

6-y=5

-y=5-6

-y=-1

y=1

Answer 2

Answer:

x = 2 and y= 1

Step-by-step explanation:

2x + y = 5 ---(1)

3x  - y = 5 ---(2)

∴ by adding equation (1) and (2), we get ,

     2x + y = 5    --------( y and -y will cancel)

(+)  3x - y = 5

-------------------

5x            = 10

  x     =     10 ÷ 5

  x     =     2

∴ substituting x  = 2 in equation (1)

2x2 + y = 5

4     + y = 5

y = 5-4

y = 1
