Algebra homework asap. what is the solution to the system of equations? x - 2y = -8 4x - 8y =10 a) use the substitution method to justify that the given system of equations has no solution. b) what do you know about the two lines in this system of equations?

A. set the top equation as x=something. you can do this by transforming functions.
answer x=2y-8
Then you substitute 2y-8 for x in the bottom problem. 4(2y-8) - 8y= 10.
Solve for y. you will get a false equation. -32=10. Proved.

B. we know that the lines are parallel. if the line don't have a solution that means that they don't intersect. that means they must be parallel because parallel lines never intersect.
