Equations can be solved in one or more steps
When the solution of an equation involves two steps, then the equation is a two-step equation.
However, if the solution involves three steps, then such equation is a three-step equation.
Two-step equation
The equation is given as:
[tex]3x +(-5) = 19[/tex]
One of the ways the above equation can be transformed to a three-step equation is as follows
[tex]3x +(-5) = 19[/tex]
Remove brackets
[tex]3x -5 = 19[/tex]
Add 5 to both sides
[tex]3x= 24[/tex]
Divide both sides by 3
[tex]x= 8[/tex]
Another way is as follows:
[tex]3x +(-5) = 19[/tex]
Collect like terms
[tex]3x = 19 - (-5)[/tex]
Evaluate like terms
[tex]3x= 24[/tex]
Divide both sides by 3
[tex]x= 8[/tex]
Three-step equation
An example of a three-step equation is:
[tex]3(x + 1) = 5 +x[/tex]
Start by opening the brackets
[tex]3x + 1 = 5 +x[/tex]
Collect and evaluate like terms
[tex]2x=4[/tex]
Divide both sides by 2
[tex]x=2[/tex]
