To be a solution of the system, it has to satisfy <em>both</em><em> the equations.</em>
<em />
Let's check first one:
3x - 2y = -1
3 (1) - 2(2) = 3 - 4 = -1
So correct (satisfies).
Now, 2nd one:
y = -x + 3
y = -(1) + 3
y = -1 +3
y = 2
Yes, this is satisfied.
Hence, (1,2) IS A SOLUTION OF THE SYSTEM
