What is the solution to #2x-y=4, -10x+5y=-20#?
1 Answer
Infinite solutions, they are the same equation and there is certainly more than one value for each.
Explanation:
#2x-y=4 " "|xx (-5)#
#-10x+5y=-20# (the same as the second equation)
The equations are identical
#{(-10x+5y=-20), (-10x+5y=-20) :}#
which means that you have an infinite number of solutions, i.e. both equations represent the same line.
