Question

What is the solution to the system of equations? A. (7,4) B. (7,13/3) C. (8,14/3) D. (9,7)

Answer 1

B. (7, 13/3)

Explanation:

Since the graph doesn't show the intersecting point, we must use algebra to solve this (Substitution or elimination).

Step 1: Substitute y

1/3x + 2 = 4/3x - 5

Step 2: Isolate x

-x + 2 = -5

-x = -7

x = 7

Step 2: Find y using x

y = 1/3(7) + 2

y = 7/3 + 2

y = 13/3
