B. (35, - 3)
C. (-35, -3)
D. (5, 3)

Answer 2

O one

Answer 3

To solve the system of equations, we can use the method of substitution.

From the second equation, we can express x in terms of y:
x = 5y - 20

Substituting this expression for x into the first equation:
-4(5y - 20) + 6y = 38
-20y + 80 + 6y = 38
-14y = -42
y = 3

Substituting this value of y back into the second equation:
x - 5(3) = -20
x - 15 = -20
x = -5

Therefore, the solution to the system of equations is (x, y) = (-5, 3).

The correct answer is A. (-5, 3).
