We have the following. 56 - (A + B)x + (A + B) We must now determine the values of A and B. There is no x term on the left side of the equation, which tells us that the coefficient for the x-term on the right side of the equation must equal 0. A +8B = 0 Setting the constant on the left side of the equation equal to the constant on the right side of the equation gives us the following. _______ = A+B Subtracting the second equation from the first allows us to determine B. B = ______
Substituting this value of B into either of the equations allows us to solve for A. A= _______
