## Two Step Linear Equation Problems

The solution to each of the following problems is 18. Focus on finding the most helpful algebraic steps to take a reader from the problem as stated to the solution.

1.   $2x+1~=~37$
2.   $5+3x~=~59$
3.   $2x+3x~=~90$
4. Continue reading Two Step Linear Equation Problems

## One Step Linear Equation Problems

The solution to each of the following twenty problems is 12. Focus on finding the most helpful algebraic step to take a reader from the problem as stated to the solution, and be sure you can explain why that step leads to a solution.

1.   $x+7~=~19$
2.   $3+x~=~15$
3.   $11~=~-1+x$
4. Continue reading One Step Linear Equation Problems

## Interactive Graphs for Linear, Quadratic, Rational, and Trig Functions Moved to GeoGebraTube

Some may have had trouble using my GeoGebra applets in their browsers. I have moved all of them to GeoGebraTube, which will hopefully fix the problem. You may search for them by typing “MathMaine” into the GeoGebraTube search box.

Links to all updated interactive graph applets are below. Comments and suggestions are always welcome!
