Inverse operations is a concept that needs to be understood because it is often used in algebra to solve variables.
We explain inverse operations as applied in numerical statements. Inspect the following example of a numerical equation, which is later translated into an algebraic equation:
21 × 5 - 10 = 95
21 × 5 = 95 + 10 (Add 10 both sides of =.)
21 = (Divide by 5 both sides of =.)
Do the following:
Following our example to the left, work through the numerical equation below and then translate it into an algebraic equation, where you solve for the unknown value:
3/5 + 13 = 20
"\\frac{3}{5}x+13=20"
"\\frac{3}{5}x+13-13=20-13"
"\\frac{3}{5}x=7"
"x=7\\times\\frac{5}{3}"
"x=\\frac{35}{3}"
"x=11.67"
