How many solutions does −3x=−x−2x and what value does it have

Answer 1

To determine this you should simplify the equation by combining all like terms on each side. The equation would then be -3x=-3x. We now see that this equation is exactly the same on each side. This means that x can be all real numbers. This is because no matter what value you put into x, the value will be the same on each side.
