5x-y=54
x=10
50-y=54
-y=54-50
y= -4
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.
