B(3, 1)
C(1, –3)
D(–1, –3)
The solution to the given system of equations is (3, –1). The correct answer is option A.
The system of equations is given as:
x - 4y = 7 ....(1)
5x + 9y = 6 ....(2)
Solve the first equation for x:
x = 7 + 4y
Substitute the value of x in the second equation:
5(7 + 4y) + 9y = 6
35 + 20y + 9y = 6
29y = -29
y = -1
Substitute the value of y back into the first equation to find x:
x = 7 + 4(-1)
x = 7 - 4
x = 3
Therefore, the solution to the system of equations is x = 3 and y = -1.
Thus, the correct answer is option A.
