Answer
a is a solution.
b is not a solution.
Work Step by Step
Check each ordered pair by replacing x and y in the system of equations.
a. 4($\frac{3}{4}$) + (-3) = 0
0 = 0; True
-8($\frac{3}{4}$) - 5(-3) = 9
9 = 9; True
b. 4(-2) + 8 = 0
0 = 0; True
-8(-2) - 5(8) = 9
-24 = 9; False
Only a satisfies both equations.
