Objective: Solve an equation.
Transform to solution equation with inverse operation.
Inverse of Multiplication is Division; Inverse of Division is Multiplication.
Transform until equation is solved: solution equation has the form

*=***x****where***k***is some number.***k*Geogebra can transform an equation IN PARENTHESES
you can add 4 to both sides by typing +4 after the parentheses.
you can subtract 3 from both sides by typing -3 after the parentheses.
Enclose negative numbers in parentheses.
Method: HOW TO DO IT
Wait for Geogebra web app to load and give you an equation.
Click in line 2, type right parenthesis (Shift 0)
You can also type a left paren ( then click line 1 then type a right paren )
Line 2 should show the line 1 equation wrapped in parentheses.
Decide on an inverse transformation, and enter it.
Line 2 should show the solution equation
Record your equation work on paper showing inverse transformations.
Click refresh (circle in upper right) to get a new equation.
Problems: IF YOU MESS UP
If Line 2 is NOT SIMPLER than Line 1, then click the button under the 2 and DELETE Line 2
OR click the whole line and DELETE it
Sometimes this doesn't work. I don't know why.
You can start from the beginning (or some other spot) by typing a left paren ( then clicking Line 1 or another good line then typing a right paren )
