Question

how to substitutethe equation
x-8=2y
x+y=-2

Answer 1

Step-by-step explanation:

x-8=2y

x+y=-2

solution: x-y=2y (1)

x+y=-2 (2)

from eqn.(2)

x=-2-y

now substitute the value of x in eqn.(1)

and after substituting you'll get the value of y then substitute again the value of y in eqn.(2).

there you'll get the value of both x and y by substituting method
