Determine whether the equation has the form x = a, and if it does, the equation has one solution.
i just took the test
there is only one solution
it would be letter c

Determine whether the equation has the form x=a, and if it does, the equation has one solution.
Jeremy can simplify the equation enough to determine if the x-coefficient on one side of the equation is the same or different from the x-coefficient on the other side. Here, that simplification is ...
-3x -3 +3x = -3x +3 +3
We see that the x-coefficient on the left is 0; on the right, it is -3. These values are different, so there is one solution.
In the attached, the left-side expression is called y1; the right-side expression is called y2. The two expressions are equal where the lines they represent intersect. That point of intersection is x=3. (For that value of x, both sides of the equation have a value of -3.)
If the equation's x-coefficients were the same, we'd have to look at the constants. If they're the same, there are an infinite number of solutions. If they are different, there are no solutions.
Determine if the equation has the form x = a, if it does then it has one solution.
We are given the following equation for which Jeremy wants to determine the number of solutions without actually solving the equation.
The best method for this would be to determine if the equation has the form where represents the variable while represents the constant.
If the equation has this form, then it means it has one solution.
