Question 197356
{{{x+9y=5}}} Start with the first equation.



{{{4-9y+9y=5}}}  Plug in {{{x=4-9y}}}.



{{{4=5}}} Combine like terms on the left side



Since the equation above is clearly NOT true, this means that there are no values of "y" that will satisfy the equation.



So there are NO solutions. This means that the system is inconsistent.
