Answer:
The smallest number is 0
Step-by-step explanation:
x + y = 20
3x - 3y = 40
solving these two equations
x = 0
y = 20
The answer to the question
Answer:
The solution for given system of equations is: x = 6 and y = 3
Or
(6,3)
Step-by-step explanation:
Given equations are:

There are three methods to solve simultaneous equations
- Elimination
- Substitution
- Co-efficient method
We will use the elimination method as the coefficients of x in both equations are already same
Subtracting equation 2 from equation 1

Putting y = 3 in equation 2

Hence,
The solution for given system of equations is: x = 6 and y = 3
Or
(6,3)
