Geogebra can transform an equation from a previous line
To work on the equation in line 1, refer to it as #1
you can add 4 to both sides of the line 1 equation by typing #1+4 in line 2
you can subtract 3 from both sides of the line 1 equation by typing #1-3 in line 2
you can multiply both sides of the line 1 equation by 5 by typing #1*5
you can divide both sides of the line 1 equation by 7 by typing #1/7
Method: HOW TO DO IT
Wait for Geogebra web app to load and give you an equation.
Click in line 2, type #1, decide on an inverse transformation, type it, then ENTER.
Line 2 should show the solution equation, or you might have to continue to line 3
Record your equation work by taking a screenshot and pasting it into the Google Doc
Click refresh (circle in upper right) to get a new equation.
IF YOU MESS UP If Line 2 is NOT SIMPLER than Line 1,
then click the button under the 2 and DELETE Line 2 with a right-click
