Question

Which statement is true for the equation 3n − 7 = 3n − 6?
A. It has no solution
B. It has one solution
C. It has two solutions
D. It has infinitely many solutions

Answer 1

m=m <---means there are infinte solutions
m=x <---No solution
x=1 <---one solution

Answer 2

Subtract 3n from both sides.
\[\huge~\rm~3n−7−3n=3n−6−3n\]−7=−6
Add 7 to both sides.
\[\huge~\rm−7+7=−6+7\]
\[\huge~0=1\]
so we have m=x case

im lost @Moe95

Answer 7

a number that doesnt equal the same number means that there is no solution
0=1 would be no solution
