what is the addition property of equality?
Equation
Two expressions set equal to each other.
Linear Equation
in One Variable
An equation that can be written in the form
ax + b = c
where a, b, and c are constants.
Note that the exponent (definition found in Tutorial 4: Introduction to Variable Expressions and Equations) on the variable of a linear equation is always 1.
The following is an example of a linear equation:
3x - 4 = 5
Solution
A value, such that, when you replace the variable with it, it makes the equation true.
(the left side comes out equal to the right side)
