Question

solve by Elimination Method
5 x + y =7 , x - y = 1
​

Answer 1

Answer:

6x = 8

x = 4/3

y = 1-4/3

y= -1/3

hope that helps !!!

Answer 2

Step-by-step explanation:

5x+y=7 (this is equation 1)

x-y=1

x= 1+y

put value of x in equation 1

5(1+y)+y=7

5+5y+y=7

6y=7-5

6y=2

y=2/6

y=1/3

x=1+y

x=1+1/3(taking LCM)

x=4/3
