Question

PLEASE HELP MEEEE!!!! x=y-1 x+2y=8 Answer-

Answer 1

Answer:

y=5 x=2 this is correct

Answer 2

Answer:

X = 2 , Y = 3

Step-by-step explanation:

Equation 1

x=y-1

Equation 1

x -y =  -1

Equation 2

x+2y=8

Multiply equation 2 by equation -1

-x-2y= -8

By elimination method

x -y =  -1

- x-2y= -8

-3 y = - 9

Y = 3

Put Y = 9 in equation 1

X - Y = -1

X  -3 = -1

X  =  3 -1

X  =  2

X = 2 , Y = 3
