Answer:
Box 1. 2x
Box 2. -13 (1/3) or (-40/3)
Box 3. 2x
Box 4. (2/3)x
Box 5. 3
Box 6. 3
Box 7. -20
Box order left to right.
Step-by-step explanation:
(5/3)x + (1/3)x = 13 (1/3) + (8/3)x
add numberator ( top number ); keep the denominator the same ( bottom number )
Line 1. (6/3)x or 2x = 13 (1/3) + (8/3)
------------------------------------------
Line 2. -13 (1/3) = (8/3)x - 2x
-------------------------------------------
Ex. 3 × (-13) = 39 - 1 = (-40/3)
--------------------------------------------
Line 3. (-40/3) = (2/3)x
---------------------------------------------
Line 4. (3) (-40/3) = (2/3)x (3)
----------------------------------------------
-40 = 2x
÷2 ÷2
Line 5. -20 = x
-------------------------------------------------
Sorry if this is a little confusing. I hope this helped!
