Answer:

No solution

Explanation:

Given


5x + 3y = 15


10x + 6y = 20

Required

Number of solutions

Using elimination method.

First, multiply equation (1) by 2


5x + 3y = 15 * 2


5x * 2 + 3y * 2 = 15 * 2


10x + 6y = 30

So, we have:


10x + 6y = 30 and


10x + 6y = 20

Subtract both equations


10x -10x + 6y - 6y = 30 - 20


0+0 = 10


0 = 10

The above equation is not true because:


0 \\e 10

Hence, the system of equations has no solution.
