Answer: Explained in the step-by-step
Explanation:
We want to isolate x, and remember, what we do to one side we do to the other:
(x+3) * 3 2/5 = 15 3/10
(x+3) * 3 2/5 divided by 3 2/5 = 15 3/10 divided by 3 2/5
x + 3 = 153/10 * 5/17
x + 3 = 765/170
x + 3 = 153/34
x + 3 = 4.5
x + 3 - 3 = 4.5 - 3
x = 1.5
Check:
(1.5+3) * 3 2/5 = 15 3/10
4.5 * 3 2/5 = 15 3/10
(3 2/5 = 3.4 and 15 3/10 = 15.3)
4.5 * 3.4 = 15.3
15.3 = 15.3
