Question

How many solution of the system?
y = 2x + 3
3 y = 6 x + 9

Answer 1

infinite number of solutions

Explanation:

Given the 2 equations

y = 2x + 3 → (1)

3y = 6x + 9 → (2)

Divide the terms in (2) by 3

y = 2x + 3 → (3)

Since the equations are the same in (1) and (3) , then

The system has an infinite number of solutions

Answer 2

Are you needing to solve the equation ? If so it’s y=2x+3
