10-12 , find the missing number and once you found the missing number and answered it you make sure it’s the solution it gave you like 10: infinitely many solutions

10. Infinitely many solutions:

Simplify this equation:

When the equation becomes

This equality is true for all x, thus the equation has infinitely many solutions.

11. The equation should have one solution x=-1.

First, simplify the equation:

This equation will have solution x=-1 when

Therefore, the initial equation is

12. The equation should have infinitely many solutions.

Simplify it:

When this equation will have infinitely many solutions.
