How do you solve trig equations that have something squared in them? In this video I show how to use a U-substitution to rewrite trigonometric equations as quadratics, which makes them easier to solve. We use the unit circle to solve...

This is the second of two videos on solving systems of equations using the substitution method.

This is the first of two videos on solving systems of equations using the substitution method. Make sure to watch "Solving Systems by Substitution 2" for help with solving systems when both equations are in standard form!

This video practices solving systems of equations by substitution and elimination.

This video explains substitution in maths within the topic of algebra and what it means to evaluate an expression. Practice questions and solutions are at the end of the video.

Are algebraic equations giving you a headache? Fear not! In this comprehensive tutorial, I'll break down the art of solving algebraic equations using opposite operations.

In this video, the teacher demonstrates how to evaluate algebraic expressions by using the substitution property to replace variables with given values. The examples cover simple expressions as well as more complex ones, guiding students...
