How many solutions does the equation -7a + 7a + 6 = 8 have? one none two many

None

Step-by-step explanation:

The first thing you ALWAYS want to do in these types of algebra questions is combine all of your "like terms," which are the parts of your equation with the same variable (or no variable).

In this case, the first thing you see to combine are the "-7a" and the "7a". When you do -7a + 7a, you get 0. Therefore, you are left with the equation 0 + 6 = 8, or simply 6 = 8.

We know that 6 doesn't equal 8, and 6 will never equal 8 regardless of what values we substitute for the variable a. Therefore, there are no solutions (where a solution is a substitution for the variable a) to the equation.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
