0.04x - 0.3 = 3.3?

0.04x - 0.3 = 3.3
100(0.04x - 0.3) = 100(3.3)
4x - 30 = 330
4x = 330 + 30
4x = 360
x = 360/4
x = 90

4x - 30 = 330
4x = 360
x = 90

.04*x= 3.3+.3
x=3.6/.04
x=3.6*100/.04*100
x=360/4
x=90

0.04x = 3.3+0.3
--> 0.04x = 3.6
-->x=3.6/0.04
-->x=90

0.04x - 0.3 = 3.3 Add 0.3 to each side to get
0.04x = 3.6 Divide both sides by .04 to get
x = 90
