Answer:

No solution

Step-by-step explanation:

Given

[tex]5x + 3y = 15[/tex]

[tex]10x + 6y = 20[/tex]

Required

Number of solutions

Using elimination method.

First, multiply equation (1) by 2

[tex]5x + 3y = 15[/tex] * 2

[tex]5x * 2 + 3y * 2 = 15 * 2[/tex]

[tex]10x + 6y = 30[/tex]

So, we have:

[tex]10x + 6y = 30[/tex] and

[tex]10x + 6y = 20[/tex]

Subtract both equations

[tex]10x -10x + 6y - 6y = 30 - 20[/tex]

[tex]0+0 = 10[/tex]

[tex]0 = 10[/tex]

The above equation is not true because:

[tex]0 \ne 10[/tex]

Hence, the system of equations has no solution.
