Answer:
Subtraction Property of Equality
Step-by-step explanation:
When solving an equation for a variable (in this case n), we want to move all of the n-terms to 1 side and the non-n terms to the other side. To do this, we can subtract 5.2 from both sides to leave 2.5n by itself. The property we used to do this is the Subtraction Property of Equality which states that if you subtract a quantity from one side of an equation, you must also subtract that same quantity from the other side of the equation.
Answer:
56x- 35y -60xy = 0
Step-by-step explanation:
1/2x+4/5y=6/7
5y + 8x/ 10xy = 6/7
7(5y + 8x)= 6 x 10xy
35y + 56x= 60xy
56x- 35y -60xy = 0
Answer:
If you mean decimal, then -0.375
