Question

Create an equation with the indicated number of solutions.
9. No solution:
3 ( x - 4/3) = 3x + ?

4/3 is a fraction fyi. What goes into the question mark that would make this equation an equation that doesn't have a solution

Answer 1

An equation that doesn't have a solution would have to end up as something impossible when you solve it all out, like
5=3.

When you simplify your equation out, you get

3x-4=3x+?

Subtract 3x from both sides.

-4=?

From this, you can tell that you need to out something in the ? that will make the equation false, or something that doesn't equal -4.

You could put anything in the ? as long as it is not -4.

Hope this helps!
