Question

solve x+y=5 2x-3y=5​

Answer 1

Answer:

(x,y) = (4,1)

Step-by-step explanation:

Given,

  x + y = 5      --1

  2x - 3y = 5  --2

Multiply --1 with 2 and subtract --2 from it

we get,

5y = 5

y = 1   --3

Substitute --3 in --1

x + 1 = 5

x = 4

Hence, x = 4 and y = 1

Answer 2

Answer

(x,y)=(4,1)

Step-by-step explanation:

x+y=5 - equation-1

2x-3y=5- equaton-2

From equation-1

x+y=5

x=5-y (equation-3)

Now putting equation-3 into equation-2

2x-3y=5

2(5-y)-3y=5

10-2y-3y=5

-2y-3y=5-10

-5y= -5

5y=5y

y=5/5

y=1

Now putting y=1 into equation-3

x=5-y

x=5-1

x=4

So (x,y)=(4,1)
