Answer:
x = (ab - ac )/c
Step-by-step explanation:
x/a = b/c - 1 Multiply through by ac:
cx = ab - ac Divide both sides by c:
x = (ab - ac )/c.
Let x = your number.
x^2 - 21 = 4x. Subtract 4x from both sides.
x^2 - 4x - 21 = 0. Factor.
(x - 7) (x + 3) = 0. Set each term to 0.
x + 3 = 0. Subtract 3 from both sides.
x = -3. This is the negative solution.
Set the other term equal to zero.
x - 7 = 0. Add 7 to each side.
x = 7. This is the positive solution.
