Question

5x-2y = 4 तथा x+8y = 26 हो, तो x+y का मान ज्ञात करो ​

Answer 1

Answer:

x= 2, y=3

Step-by-step explanation:

5x-2y=4 eq.(1)

x+8y=26 eq.(2)

Multiplying eq.(2) by 5, we get,

5x+40y=130 eq.(3)

5x-2y=4 eq.(1)

Subtracting eq.(1) from eq.(3), we get,

42y=126

y=126/42

y=3

Substituting 'x' in eq.(1), we get,

5x-2y=4

5x-2(3)=4

5x-6=4

5x=10

x=10/5

x=2

Therefore, x=2 and y=3
