fill in the blanks to solve the following equation: -5x-x+15=-3(2x-5)

step 1- distributive property ______
step 2- Combine like terms ______
step 3- how many solutions ______
step 4- why is there that many solutions ______
here are the options you need to use to fill in the blanks:
-5x+15=-6x-5
one solution
-5x-x+15=-6x+15
Because you can continue to solve for 1x = ___ without the variable canceling
-6x+15=-6x+15
infinite solutions
Because the variables would cancel and you would be left with a true equality
-5x-x+15=-6x-5
Because the variable will cancel, but you end up with an equality that is not true
no solution

step 1- distributive property: -5x-x+15= -6x+15

step 2- Combine like terms: -6x+15= -6x+15
step 3- how many solutions: infinite solutions
step 4- why is there that many solutions: Because the variables would cancel and you would be left with a true equality
