Question

on solving x+2y=-1 and x+y=3,the value of x and y are​

Answer 1

Answer:

x value is 7 and y value is -4

Step-by-step explanation:

x+y=3

so, x= 3-y

so by substituting the equation to x+2y= -1

(3-y) + 2y= -1

3-y+2y= -1

-y+2y= -1-3

y= -4

So now putting y's value in x=3-y

x= 3-(-4)

x=3+4

x=7

Hence, X=7 and Y= -4
