In the linear equation given below say whether the equation has exactly one solution or infinitely many solution or no solution. Now if you have more then one unkn. Write an equation that has no solution.
Subtract 2x from each side.
Use the substitution method to solve for the solution set. There are many different ways to solve a system of linear equations. Notice in the equation 3x 3 x 13 the solution 5 is not evident by inspection but in the equation x 5 the solution 5 is evident by inspection. Thus 3x 3 x 13 3x x 10 2x 10 and x 5.
