Question

5x+7y=50
7x+5y=46 geography with SE HAL karo​

Answer 1

Answer:

X= 3Y=5

Step-by-step explanation:

5x+7y =50

5x=50-7y

x= (50-7y)/5. equation 1

putting value of x from equation 1 below

7x+5y=46

7(50-7Y)/5+ 5Y= 46

350-49Y/5 + 5Y= 46

350-49Y+25Y/5=46

350-49Y+25Y=230

350-24y=230

-24y= 230-350

-24y= -120

y=5

putting value of y in equation 1

x= 50-7y/5

x=50- 7*5/5

x= 50-35/5

X= 15/5

X=3
