Question

3x-2y=-1 Y=-x+3 is (1,2) a solution of the system

Answer 1

Yes

Explanation:

To be a solution of the system, it has to satisfy both the equations.

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
