Subtract 45 to both sides

-5=-0.2x

now divide -0.2 to both sides

-5/-0.2=x

A negative divdes by a negative gives you a positive

5/0.2=x

You can leave that like that or find the decimal form of it.

0.2x = 45 - 40

0.2x = 5

x = 5/0.2

x = 25

Checking:

40 = -0.2x + 45

40 = -0.2 (25) + 45

40 = -5 + 45
