Question

What does it mean when the result of solving a linear equation is x = 0?

Answer 1

if you get \(\huge\color{green}{{\rm x = }}\) something then one solution
and if you get both side equal for example \(\huge\color{green}{{\rm 0= 0}}\) then many solution (infinite manyy solution)
and if both side are not equal like \(\huge\color{green}{{\rm 5 = 10}}\) then no solution
