Distribute the -2 first on the right side of the equation -3x-4=-2x+(-4)-x -3x-4=-2x-4-x Then add all like terms -3x-4=-3x-4 Put all like terms on the same side ( variables on one side and constants on one side) when doing that remember when move a term from the original position it changes sign. -3x+3x=4-4 0=0 There is no solution for x.
