Solve 5x - 6y = - 38

3x + 4y = 0

Choices are:

A) (4,3)

B) (-4,3)

C) (4,-3)

D) (-4,-3)

(-3) * (5 x - 6 y) = (-38) * (-3)

5 * (3 x + 4 y) = 0 * 5

You will have

-15 x + 18 y = 114

15 x + 20 y = 0

you add 2 equations together

You will have

38 y = 114

y=3

Then you chance y = 3 in equation 2, you will have

3 x + 4 * 3 = 0

3 x = - 12

x = - 4

You have x = - 4 and y = 3

(-4,3)
