Answer:

x = −21.25

Explanation:

0.4(-0.2x - 3) = 0.5

distribute the .4

.4 * -0.2 = -0.08x and 0.4 * -3 = −1.2

we now have -0.08x - 1.2 = 0.5

next we add 1.2 to both sides

-0.08x - 1.2 + 1.2 ( these two 1.2's cancel out ) = 0.5 + 1.2 ( 0.5 + 1.2 = 1.7)

we then have -0.08x = 1.7

We then divide both sides by -0.08

-0.08/-0.08 = x

1.7 / -0.08 = −21.25

we're left with x = −21.25
