Answer:
The symmetric property
Step-by-step explanation:
The symmetric property of equality says we can exchange the sides of an equation and it will still be true..
In symbols, it says
If a = b, then b = a.
Your statement is
If 8x = 5y - 3z, then 5y -3z = 8x
Let a = 8x and b = 5y - 3z and your statement becomes
If a=b, then b=a
It is an example of the symmetric property of equality.
If its an even number its divisible by 2 if you add the answer (7+8) and it equals a number (7+8=15) divisible by 3 then 78 is divisible by 3 and if it is divisible by both 2 and 3 then you know it is divisible by 6 but you have to be able to divide the number by BOTH 2 AND 3
No solution 7x square and -3 cant equal you a positive or a negative answer
