Hope this answers the question. Have a nice day.
Answer:
No solution
Step-by-step explanation:
Given two equations are 2x+4y= -8 and 4x+8y= 5
These two lines are parallel They don't have a solution because they do not meet .
Multiply the first equation by 2 we get 4x+8y = -16
the other equation is 4x+8y= 5 clearly these two are parallel .
To prove by elimination method we have subtract those two equations we get 21≠0 which is not possible.
Therefore there is no solution to the given set of equation.
