Question

4x+3y=14 ; 5x+7y=11​

Answer 1

Answer:

4x+3y=14 ............ (i)

5x+7y=11 ..............(ii)

From eq. (i), we have,

4x+3y=14

=> 4x=14-3y

=> x = 14-3y ............ (iii)

4

Now, putting the value of x from eq. (iii) in eq. (ii) we get,

5x+7y=11

=>5(14-3y)+7y=11

4

=>70-3y+7y=11X4

=>70+4y=44

=>4y=44-70

=> y = -26

4

Since, y = -26

4

So, x=14-3y

4

x=14-3X(-26)

4X4

x=11X(-26)

16

x= -286

16

Therefore, x = -286 and y = -26
