Respuesta :
The answer is infinite, many solutions. That means there can be any value of b.
Let's try to solve for b.
First distribute...
4b - 4 = -4 + 4b
Combine like terms...
4b - 4b = -4 + 4
0 = 0
This tells us that the two equations (4b - 4 = -4 + 4b) are the same 2 lines. Therefore, there are an infinite number of solutions. Test it by substituting various numbers for b. They all work.
So is there only one solution? No. There are infinite solutions.
