Step-by-step explanation:
To determine if (3, 1 ) is a solution to the system
Substitute x = 3 into both equations and evaluate. If the result is y = 1 for both then the point is a solution.
y = × 3 - 3 = 4 - 3 = 1
y = - 2(3) + 7 = - 6 + 7 = 1
Since both equations equal 1 then
(3, 1 ) is a solution to the system
