Answer:
x = −21.25
Step-by-step 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
