Answer:
Subtraction Property of Equality.
Step-by-step explanation:
To solve x + 8 = 9, you need to subtract 8 from both sides of the equation. So, you would be using the Subtraction Property of Equality.
Hope this helps!
Add 7 to both sides
3x + 12 = 7x
Subtract 3x
12 = 4x
Divide by 4
x = 3
10 / 1 is a rational and which is equal to 10 so 10 is also a rational number
X is equal to 8
Y is equal to 0
