# 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.
