0.8-4x=-0. y 6x+4.0y=4.2

Which of the following shows the system with like terms aligned?

-4x - 0.4y = - 0.8

6x + 0.4y = 4.2

-4x + 0.4y = 0.8

6x + 0.4y = 4.2

-4x + 0.4y = - 0.8

6x + 0.4y = 4.2

-4x + 0.4y = - 0.8

6x - 0.4y = 4.2

C, The answer is C.

We have been given the equations:

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

We need to determine the system of equations with like terms aligned. Hence, x and y values should be at the same side of the = sign and the constant should be at the other side

⇒ System of equations with aligned terms is:

- 4x + 0.4y = - 0.8 AND

6x + 0.4y = 4.2

This above system matches with the third option given in the question.
