GRE Math Practice: Solving Equations and Angles - Plugging In Technique

Assalamu Alaikum
Welcome to Doct Maths!
In this video, we tackle two essential GRE math questions using effective techniques.
Question 5: We start with solving the equation 7(q−r)=107(q − r) = 107(q−r)=10 to find qqq in terms of rrr. Learn the step-by-step process to isolate qqq and master algebraic manipulation.
Question 6: Next, we dive into geometry to understand how to express an external angle aaa in terms of the internal angles bbb and ccc. Using the figure provided, we demonstrate the relationship between exterior and interior angles in a triangle.
By watching this video, you will:
• Enhance your algebra skills with practical examples.
• Gain a deeper understanding of geometric principles.
• Learn how to apply the Plugging In technique to simplify complex problems.
