x = 1.5
Step-by-step explanation:
-1.2 (3 - x) = -1.8
<em>Apply distributive property</em>
-3.6 + 1.2x = -1.8
<em>Get 1.2x alone so add -3.6 to each side</em>
1.2x = 1.8
<em>Get x alone so divide 1.2 on each side</em>
x = 1.5

ΔABC ~ ΔADE
AC/AE = AB/AD
AC/(AC+15) = 8/18
18AC = 8(AC+15)
18AC = 8AC + 120
18AC - 8AC = 120
10AC = 120
AC = 120/10
AC = 12
