What is the solution to \(-3 ( x-5) = -2x + 4\)? Let's first talk about the linear equation, y=5 do that is we can add six. I was working through this problem for PRACTICE: DETERMINE THE CONDITION FOR NO SOLUTION, but I don't understand why you can claim that 3ax=6x and ignore the -11 and +6. Algebraically, it means that there is some way to remove the variable completely from both sides of the equation so that you end up with a false statement, like 2 = 3. Linear inequality and linear equation - A linear inequality resembles in form an equation, but with the equal sign replaced by an inequality symbol.
