So, the first 10 suits came with a commission of 5%, so for each suit it was:
250*5%
this is
but this counts for 10 suits, so together his commssion was 10*12.5=125 dollars
and the "extra" 3 suits came with a comittion of 5+3 percent, so 8 percent, which is
for each suit, and 60 in total.
his total comission was 125+60=185 dollars.

No, we do not multiply the first equation by 2 and then add it to the second equation. We have to multiply the first equation by 4.
To illustrate this point, consider system A:
If we multiply the first equation by 2, we get
Now, if we replace the second equation with the sum of the second equation and , we get
which simplifies to
This is not an equivalent system to System B. We can see that we ended up with a 2y = 4 equation.
In order to end up with a 2x = 10 second equation, we have to multiply the first equation of system A by 4 to get
If we replace the second equation with the sum of the second equation and , we get
which simplifies to
Otherwise, you are correct. The solution to system B is the solution to system A. Adding an equation to another does not change the system.
