Solve the system of equations.

0.8x + 0.1y = - 2

-0.17x + y = - 3.66

A (4, 2)

B (2, 1)

C (-2,-4)

D (-10, 12)

E (-12, 12)

A).8x +.1y = -2

B) -.17x + y = - 3.66

We multiply A) by - 10

A) - 8x - y = 20 then add it to equation B)

B) -.17x + y = - 3.66

-8.17x = 16.34

x = - 2

-1.6 +.1y = - 2

.1y = -.4

y = - 4

Answer is C)
