The ordered pair (2, 3) is not a solution to 3x + 4y = 18
The ordered pair (2, 3) is a solution to 2x - 2y = 2
How to determine the true statement about the ordered pair
From the question, we have the following parameters that can be used in our computation:
3x + 4y = 18
2x - 2y = 2
This can be expressed as
3x + 4y = 18
x - y = 1
So, we have
x = y + 1
Substitute the known values into the equation
3(y + 1) + 4y = 18
3y + 3 + 4y = 18
So, we have
7y = 15
Evaluate
y = 15/7
Hence, the ordered pair is not a solution to the system of equations
