0.8 - 4x = -0.4y
6x + 4.0y = 4.2


Which of the following shows the system with like terms aligned?
a.) -4x - 0.4y = -0.8 6x + 0.4y = 4.2
b.) -4x + 0.4y = 0.8 6x + 0.4y = 4.2
c.) -4x + 0.4y = -0.8 6x + 0.4y = 4.2
d.) -4x + 0.4y = -0.8 6x - 0.4y = 4.2

Respuesta :

C -4x + 0. 4y = 0. 8

6x + 0. 4 y = 4. 2

how can subtracting the equations help you solve the system?

B: It eliminates the y-terms

The solution to the system is

( 0.5, 3)

Answer:

c.) -4x + 0.4y = -0.8 6x + 0.4y = 4.2
