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