A set of equations is given below: Equation E: a = 5b + 1 Equation F: a = 3b + 4 Which statement describes a step that can be used to find the solution to the set of equations? Equation F can be written as 5b + 1 = 3b + 4. Equation F can be written as b + 1 = 3b + 4. Equation F can be written as a = 3(a − 1) + 4. Equation F can be written as a = 5(a − 4) + 1.
