Question

solve only by substitution method​

Answer 1

Answer:

X+y=8(first equation)

2x-3y=1(second equation)

X=8-y

put this value in second equation

therefore,2(8-y)-3y=1

16-2y-3y=1

16-5y=1

-5y=1-16

-5y=-15

y=3

put this value in first equation to find x

therefore,X+3=8

X=5

Answer 2

Step-by-step explanation:

x+y=8

x=8-y ------(1)

2x-3y=1

substituting eq 1.

2(8-y)-3y=1

16-2y-3y=1

-5y=-15

*y=3*

from eq 1

x=8-y

x=8-3

*x=5*
