_____
The associative and commutative properties of multiplication let you put the factors (7)(1/8)(x) in any order or grouping you like.
Here, instead of (7·1/8)·x, the question is offering the rewrite 7(1/8·x), a straightforward application of the associative property.
Answer:
-4.25
Step-by-step explanation:
When x = -1, the equation is 5(-1) - 8y = 29. This simplifies to -5 - 8y = 29. Add 5 to both sides to get -8y = 34. Divide -8 from both sides to get y = -4.25.
