Question

solve the following Simultaneou
equations :
2x-y = 5; 3 x + 2y = 11​

Answer 1

Step-by-step explanation:

2x-5=y

And,

3x+2(2x-5)=11

3x+4x-10=11

7x=11+10

7x=21

x=3

Again,

y=2×3-5

6-5

1

Answer 2

Answer:

x=3 and y=1

Step-by-step explanation:

Given,

2x-y = 5 or y = 2x-5........(1)

and 3x+2y = 11

or 3x+2(2x-5) = 11. {using (1)}

or 3x+4x-10 = 11

or 7x = 11+10

or x = 21/7

or x = 3.

Now, y = 2×3-5 = 6-5 = 1.
