Answer:
Step-by-step explanation:
A solution is usually thought of as the intersect points of the graph with the x axis. So you have to make a guess here. I don't think you can get an exact answer.
The left solution looks like it is about 2/3 the way to three, so that would make the answer about - 2.67
The right solution looks about the same: 2/3 the way to 3 os the answer there would be 2.67
