Solve Systems of Equations FAST on the SAT with Desmos

When SAT test day is near, every second counts. At Sharpe Sessions, we don’t just teach math—we teach strategy. If you’re prepping with a math tutor or working with an online SAT tutor, here’s one SAT hack we love to share:

Use Desmos to Solve Systems of Equations — Fast and Accurately.

Wait, What’s Desmos?

Desmos is a free, graphing calculator tool built right into the SAT’s digital platform. And trust us—it’s a game changer.

Here’s How to Use It Like a Pro

Let’s say the SAT gives you a system like:

y = 2x + 1
y = -x + 4

Instead of solving it algebraically, open the Desmos graphing tool and:

1. Type both equations in.

2. Look for the point of intersection.

✅ That point is your solution. Easy.

Why It Works So Well

• Visual learners love it — seeing the graph helps concepts click.

• It reduces algebra mistakes — no need to manually substitute or eliminate.

• It saves time — solve in seconds, not minutes.

This is one of our favorite time-saving strategies as SAT tutors in Atlanta, Conyers, and even for our students working with a SAT tutor in Jamaica.

Real Practice, Real Results

During one of our summer prep sessions, a student said,

“Desmos made solving systems of equations so much faster. I got three extra questions done that I wouldn’t have had time for.”

That’s what we love to hear! When strategy meets preparation, you get results.
