Question 1205381
<font color=black size=3>
If we want to check if (4,1) is a solution, then we plug x = 4 and y = 1 into both equations to see if we get a true result or not.
Both equations need to be true or else it's not a solution.


Plug the values into the 1st equation.
9x - 10y = 26
9*4 - 10*1 = 26
36 - 10 = 26
26 = 26
We arrive at a true statement, so the 1st equation is true.


Now let's work on the 2nd equation.
3x - 11y = 1
3*4 - 11*1 = 1
12 - 11 = 1
1 = 1
This is true as well.


<font color=red>Both</font> equations <font color=red>are true</font> when x = 4 and y = 1.
We have confirmed that <font color=red>(4,1) is indeed a solution</font>
