<span> 1.5(0.8x-1.2) = 0.2x+1.2
1.2x-1.8=0.2x+1.2
+1.8 +1.8
1.2x=0.2x+3
</span>
1.2x=0.2x+3
-0.2x -0.2x
x=3

Answer:
Here you go
Step-by-step explanation:
(3 x 10) x 8 = x(10 x 8)
What you do the distributive property so multiply 3x10 and you get 30 and multiply by 8 you get 240 so one side is solved. Now multiply 10x8 you get 80 and remember to multiply the variable x so you get 80x=240 now divide 80 both sides and you will get 3 as your total answer
