Given the following equation:
[tex]4b-1=-4+4b+3[/tex]You can follow the steps shown below in order to solve for the variable "b":
1. You can add the like terms on the right side of the equation:
[tex]4b-1=4b-1[/tex]2. You can observe that the left side of the equation is equal to the right side, so if you solve for "b" its coefficient will be zero:
[tex]\begin{gathered} 4b-4b=-1+1 \\ 0=0 \end{gathered}[/tex]This is a statement that is always true. When this happens, the solution of the equation is all the Real numbers.
Therefore, the answer is: The equation has an infinite number of solutions.
