Answer:
x = 14 and y = 10
Explanation:
TRANSLATING WORDS INTO EQUATIONS:
Let the two numbers be x and y
"The sum of two numbers is 24" translate as x + y = 24
"Their difference is 4" translates as x-y=4
Those two equations make up the system of linear equations
SOLVING BY ELIMINATION:
Adding the two equations, we get
x + y + x - y = 24 + 4
2x = 28
x = 28 / 2
x = 14
substituting that into x + y = 24 we get
14 + y = 24
y = 24 - 14
y = 10
