Question

2x+y=8 &x+y=5 nakhsa vidhana​

Answer 1

Step-by-step explanation:

• 2x+y=8-------(1)
• x+y=5---------(2)

From eq(2)-

➝x+y=5

➝x=5-y-------(3)

• Substituting the value in eq (1)

➝2x+y=8

➝2(5-y)+y=8

➝10-2y+y=8

➝10-y=8

➝y=8+10

➝y=18

• Substituting the value in eq (3)

➝x=5-y

➝x=5-18

➝x=-13
