Use the expressions below to create one equation that has exactly one solution, one equation that has no solutions, and one equation that has infinitely many solutions. Each equation should use two of the expressions—one on each side of the equals sign.

A. 0.5(60)x+5 0.5 left parenthesis 60 right parenthesis x plus 5

B. 0.65(50)x 0.65 left parenthesis 50 right parenthesis x

C. 45x − 0.75(20)x+5 45 x space minus space 0.75 left parenthesis 20 right parenthesis x plus 5

D. 1.5(10)x+15(x+1)−5 1.5 left parenthesis 10 right parenthesis x plus 15 left parenthesis x plus 1 right parenthesis minus 5

Explain how you know each equation has one, none, or infinitely many solutions.
