Question

3x+4y = 11
5x-2y = 1

Find x and y ​

Answer 1

Answer:

x = 1 and y =2

Step-by-step explanation:

3x + 4y = 11

(5x - 2y = 1) multiplying this eq by 2  gives     10x - 4y = 2

adding these two eqs

3x + 4y = 11

10x - 4y = 2     we get     13x = 13

therefore x = 1

Putting the value of x in any equation we get the value of y as

3(1) + 4y = 11

4y = 11 - 3

4y = 8     y = 2

Answer 2

Answer:

value of x is 1

& value of y is 2

Step-by-step explanation:

3x + 4y = 11. (1)

5x - 2y = 1. (2)

multiple by 2 to equation (2)

so it will become

10x -4y = 2 (3)

now,

adding equation (1)&(3)

3x + 4y = 11

10x - 4y = 2

= 13x = 13

x= 1

puting value of x in equation (1)

3(1) +4y =11

3 + 4y = 11

4y = 11-3

y= 8/4

y =2

value of x is 1

& value of y is 2
