Â
An equation in mathematics is an equality which
contains one or more variables.
 Solving equations
consist of determining which values of the unknowns make the equality true. Â Variables are also called as unknowns. Solutions
are values which satisfy the equality .
Example:
Which
equation is a related equation for this equation 23/a=8?
a. a+8=23
b. a=23/8
c. a=23*8
d. a=8/23
The
answer is letter b. a= 23/8.How do we get letter b?
Here's how:Â
23/a
= 8/1
8a/8= 23/8
(Cancel two 8s, both the numerator and denominator, a remains.) so,
a=
23/8
