-1.8=4.6-0.4s

1 answer

To solve this equation, we need to isolate the variable 's'. Let's perform the necessary steps:

-1.8 = 4.6 - 0.4s

Add 0.4s to both sides:

-1.8 + 0.4s = 4.6 - 0.4s + 0.4s

Simplify:

0.4s - 0.4s = 4.6 - 1.8

0 = 2.8

This equation is not possible. There is no value of 's' that can satisfy it.
