Solve 2×2 System of Equation – Step by Step – using TiNSpire CX

When solving

x-5y =6

with the TiNspire CX CAS  you can either use the Substitution or the Elimination Method.

Let us demonstrate how to use the Substitution Method using the STEP BY STEP EQUATION SOLVER first:

Now, to use the Elimination Method select option 1,8 :

Below watch the Steps  to solve the system of equations using the Elimination Method:

It always works! Always get correct solutions. And you get to select YOUR method of choice.

“Physics Made Easy app was an essential piece on my way to a 5 on the AP Physics 1 exam”

The Physics Made Easy app was an essential piece on my way to a 5 on the AP Physics 1 exam.

It allowed me to feel more confident doing a variety of problems, especially projectile and rotational motion.

While the app’s features of forces (e.g. friction), electricity, simple harmonic motion, etc. were extremely helpful, the problems I encountered throughout my physics courses were relatively basic in comparison.

The aforementioned problems became trivial with the help of this app.

The app also allowed me to cut off several minutes of pesky checking on long projectile and rotational motion problems.

It was very useful to get a step by step display of the problem if I got it wrong on an assignment or a practice test, for example.
