Question

How many solutions does each of the following equations have?
3(x-7)+4=x-1

Answer 1

1

Explanation:

It is a linear equation, so it has 0 or 1 solution (or infinitely many).

You could view this one as the intersection of line y=3(x-7)+4 and the line y=x-1. There is one intersection, and it is at x=8.
