z=z
OpenStudy (nincompoop):
identity property
Nnesha (nnesha):
subtract 4 both side and 5z
Nnesha (nnesha):
4 and 5z should cancel out then you have left 0 =0 which mean ???
not one solution

there is an infinite number of solution
that is any value can be Z
OpenStudy (anonymous):
so it would be B
OpenStudy (nincompoop):
uhhh don't listen to her
Nnesha (nnesha):
nope when you get both side equal 0=0
or -6=-6 its mean an infinite number of solutions
OpenStudy (nincompoop):
no solution would mean you didn't reach an equality

no solution when 4 = 8
when both side are not equal
Nnesha (nnesha):
hope thats help :)
OpenStudy (anonymous):
oh so it would be C then yes @nincompoop @Nnesha
Nnesha (nnesha):
yesh
OpenStudy (nincompoop):
whenever you see an identity
z = z
z+1 = z+1
50z + 10 = 10 + 50z
they're all offer you an infinite set of solution
meaning that any value can replace z and you would still reach an equality
