1. distribute
step 1: 3 3
----- × X = ------X
5 5
3 5 3 Ima convert this into a decimal
------- × - ----- = - ------ ----> negative .375
5 8 8
2. write the problem now
3 1 7
----- X - 0.375 = ---- - X + ----
5 12 8
3. I would convert them into decimals and solve
0.6x - 0.375 = 0.08 - x + 0.875
+x +x
--------------------------------------------------
1.6x - 0.375 = 0.08 + 0.876
1.6x - 0.375 = 0.956
+0.375 +0.375
--------------------------------------------------
1.6x = 1.331
------ -------
1.6 1.6
---------------------------------------------------
x = 0.831875
rounded up : 0.83
