Solving One-Variable Equations with Systems

Question 5 • [INMT3] Integrated Math 3 Sem 1 (26-27)

What is x2 + 6x = x2 – 6x as a system?

Answer

y = x2 + 6x y = x2 – 6x

y = –x2 + 6x y = x2 – 6x

y = –x2 – 6x y = x2 – 6x

To write x² + 6x = x² − 6x as a system, set each side equal to y. This gives y = x² + 6x and y = x² − 6x, which matches choice A.
