Answer:
1. The two numbers are 4 and 8.
Step-by-step explanation:
1) variables: x and y
2) x + y = 12, y - x = 4
3) graph using desmos or another graphing calculator
4) the solution is x = 4, y = 8, or 4 and 8. This means that 4 and 8 can be added to equal 12, and the difference between them is 4.
Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables
Just plot the points on the graph.
2. You know since the graph is a straight line, the ratios are proportional and therefore equivalent
