Question

Solve -0.4k - 6 = 1.2. Explain your answer.

Answer 1

Answer:

k=-18

Step-by-step explanation:

To solve this, we need to isolate the variable k.

-0.4k-6=1.2

We can add 6 to both sides first.

-0.4k=7.2

Recall that what you do to one side of an equation you have to do to the other side too, so the equation remains equal.

Next, we can divide both sides by -0.4

k=-18
