Question

How many solutions can be found for the equation 3y + 5 − 2y = 1

Answer 1

We can solve the equation to find it's number of solutions, but we already know it only has 1 solution because it is a linear equation (y is raised to the first power).

`3y + 5 - 2y = 11`

`y + 5 = 11`

`y = 6`

This confirms that there is only 1 solution.
