3y = 5x + 30
y + 5x = 50 .......(1)
3y - 5x = 30 .....(2) - rearranging the first equation.
Add (1) and (2):-
4y = 80
y = 20
Now plug y = 20 into equation (1):-
20 + 5x = 50
5x = 30
x = 6
The 2 numbers are 6 and 20.
Negative 45 or -45 because different signs with multiplication are always negative

The summary of the ruler placement postulate is given as:
- there is a one-to-one correspondence between the set of points on the line and the set of real numbers, and.
- the distance between two points equals the absolute value of the difference between the corresponding numbers.
<h3>What is the ruler placement postulate?</h3>
This states that the points of a line can be matched and correspond to a set of points on the line and the set of real numbers,
