Question #437c3

Answer 1

the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formula and equations.

Explanation:

Algebra is most commonly used with missing number and variables. It uses equations that need to be solved in order to find a missing length, value, weight, etc.

Example:

If `10=2x-2`, what is the value for `x`?

To solve this you must first add the `2` to both sides.

`10color(red)(+2)=2x-2color(red)(+2)`

`12=2x`

The you divide the both sides by `2`

`12/color(red)(2)=(2x)/color(red)(2)`

So `x=6`

Hope this helps a bit!
