Question 8 • AZ-Common Core Algebra II A
The equation sets the two line expressions equal: 3x + 5 = 2x − 7. The x-value that makes them equal is the x-coordinate where the lines y = 3x + 5 and y = 2x − 7 intersect. Solving gives x = −12, so the solution is the x-coordinate of their intersection point: choice A.
