How many solutions are there for the following equation? Why?
8(x + 9) = 72 – 5x
Select the option that correctly answers both questions.

1 There is one solution, because the coefficients of the variables on both sides of the equation are different.

2 There is one solution, because the coefficients of the variables on both sides of the equation are the same.

3 There are no solutions, because the coefficients of the variables on both sides of the equation are different.

4 There are no solutions, because the coefficients of the variables on both sides of the equation are the same.
