Definition of Linear Equations
A Linear Equation is used when power of any constant unknown variable is one and the variable has one or more than one. Linear equation has the form: ax+b=0
- If a=b then a+c=b+c for any c. All this is saying is that we can add a number, c, to both sides of the equation and not change the equation.
- If a=b then a−c=b−c for any c. As with the last property we can subtract a number, c, from both sides of an equation.
- If a=b then ac=bc for any c. Like addition and subtraction, we can multiply both sides of an equation by a number, c, without changing the equation.
- If a=b then a/c=b/c for any non-zero c. We can divide both sides of an equation by a non-zero number, c, without changing the equation.
