QNT 501 EXAM 7.
QNT 501 EXAM 7.1. Solve for the unknown in the equation. 11A = 77 Divide both sides of the equation by the known factor to isolate the unknown value. 11 A 11 = 77 11 Now simplify. A= 7 Check. 11(7) = 77 77 = 77 Therefore, the solution of the equation is 7. 2. Solve for the unknown in the equation. B + 5 = 21 Subtract the known value from both sides of the equation to isolate the unknown value. B + 5 (5) = 21 (5) Now simplify. B = 16 Check. 16 + 5 = 21 21 = 21 Therefore, the solution of the equation is 16. 3. Solve for the unknown in the equation. X 53 = 27 Add the known value to both sides of the equation. X 53 + (53) = 27 + (53) Now simplify. X = 80 Check. 80 53 = 27 27 = 27 Therefore, the solution of the equation is 80. 4. Solve for the unknown in the equation. 5(X - 4) = 25 Eliminate the parentheses. 5X 20 + (20) = 25 + (20) Now simplify. 5X = 45 Divide both sides of the equation by the known factor to isolate the unknown value. 5X 5 = 45 5 Now simplify. X=9 Check the solution by substituting the answer in the original equation and verifying that a true statement result. The answer checks, so the solution of the equation is 9.
