Solve the following system of equations
Yanka [14]

Answer:

(x=3,y=-9)

Step-by-step explanation:

The given systems is;

1.2x + 2.4y =  - 18 \\  - 0.8x + 0.4y = 6

Divide the top equation by 1.2 and the bottom equation by by 0.8 to get:

x + 2y =  - 15 \\  - x + 0.5y = 7.5

Now add both new equations:

2y + 0.5y = 15 +  - 7.5

2.5y = 7.5

x =  \frac{7.5}{2.5} = 3

Let us substitute x=3 into x+2y=-15 and solve for y.

3+2y=-15

2y=-15-3

2y=-18

y=-9

The solution is (x=3,y=-9)
