Answer:
5x - 6 = 5x - 7
5x - 6 = 5x - 6
5x - 6 = 9
Explanation:
When you are looking for an equation with no solution, you only have to change the number without the variable. (5x - 6 = 5x - 7)
When you are looking for an equation with many solutions, you only have to write the exact same thing on the other side. (5x - 6 = 5x -6)
When you are looking for one solution, you don't use a variable and you only have to put a number that will give you a solution. (5x - 6 = 9)
