Question

When graphed, which of the following is the solution of the given system below?

-3=-y-4x

0=6-2y-8x

a.(2,-5)

b. (1,2)

c. (2,-2)

d. Infinite number of solutions

Answer 1

None of the above.

Explanation:

-3 = y - 4x

Thus y = 4x - 3

0 = 6 - 2y - 8x

2y = 6 - 8x

Thus y = 3 - 4x

4x - 3 = 3 - 4x

8x = 6

x = 8/6 = 4/3

y = 4 × 4/3 - 3 = 7/3

Should be (4/3, 7/3)

Hopefully this answer helps you :)
