jim_thompson5910 · Answer

When you get an equation like 0 = 24, that means the system is inconsistent. This is assuming you did everything correctly.

jim_thompson5910 · Answer

An inconsistent system has no solutions.

jdoe0001 · Answer

as jim_thompson5910 said, it'd be inconsisten and thus has no solutions

if you solve the 1st equation for "y", what do you get?

anonymous · Answer

i get y=87

jdoe0001 · Answer

87?    whatever happened to "x"?   it went "missing in action"

anonymous · Answer

for the first equation i get y=7+4x  i thought you meant what y is when you're already substituting x for y

jdoe0001 · Answer

ohh yes

jdoe0001 · Answer

.... actually... you're correct    it does give 0 = 24

that means as jim_thompson5910    said

is inconsisten or has no solution
