In the same wasy as you solve equations except that if you multiply or divide both sides by a negative number, then the inequality changes direction.
Solve using the quadratic formula
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
Solve, using the Rule of 72 rate = 4%, years = 18, fv=$8,000. Solve for PV. Formula: PV = $1/(1+r) t PV = $8000/(1+.04) 18 PV = $8000/2.0258 3949.03 = $8000/2.20258
Addition and subtraction are inverse operations. So you can solve addition by subtracting.
We can solve the mystery.
divison is like subtraction
