Question

ar
7. x + 3y = 11, 4x + 7y = 29​

Answer 1

Step-by-step explanation:

the ans is x=-0.3 approximately then y=4.3 approximately

Answer 2

Answer:

x=2 and y= 3

Step-by-step explanation:

(taking eq1)

x= 11-3y

(now, putting value of x in eq2 )

4(11-3y)+7y=29

44-12y+7y= 29

-5y= 29-44

-5y=-15

y= 3

(now,put the value of y in again in eq1)

x+3(3)=11

x=11-9

x= 2
