Question

Jeremy wants to determine the number of solutions for the equation below without actually solving the equation. -3(x+1)+3x=-3(x-1)+3 Which method should Jeremy use?

Answer 1

Answer:

Determine whether the equation has the form x=a, and if it does, the equation has one solution.

Answer 2

He should use the checking the degree of the equation method.

The given equation is: $-3(x+1)+3x=-3(x-1)+3$

This is a linear equation. The highest degree of x is = 1.

So there will be only one solution of this equation.

Hence, he should use the checking the degree of the equation method.
