Solving One-Variable Equations with Systems

Question 5 • EAP-Algebra Functions and Data Analysis A CR

Rewrite 7x + 4 = x – 2 as a system.

Answer

y = –(7x + 3) y = –(x – 2)

y = (7x + 4) y = –(x – 2)

y = (7x + 4) y = x – 2

To rewrite the equation as a system, set each side equal to y: y = 7x + 4 and y = x − 2. These two equations form the system, which is choice C.
