The expressions are not equivalent
What I would do is draw out a number line and draw a line above the fractions 5/8 and 3/8, to show the differences. I hope this helped. :)

3+4x - 8
Combine like terms
4x +3-8
4x -5
The product is the result of an multiplication which means when have to multiply:
6 * 5 * m = 30m
The multiplication ends there since there is no given value for m.

Answer:
13 (1 Ounce weights)
Step-by-step explanation:
Unit of conversion: 1 Pound =16 ounce
3 Pounds = 3 x 16 =48 Ounce
Therefore:
- Julius put 48 Ounce on one side side of scale.
- Abel put 35 1 ounce weight on the other side .
Let the number of 1 Ounce weight needed by Abel =x
Then, to balance the scale, the expression below holds.
48=35+x
Subtract 35 from both sides
48-35=35-35+x
x=13
Abel needs 13 more 1 Ounce weights to balance the scale.
