Question

How do you write a system of linear equations in two variables? Explain this in words and by using mathematical notation in an equation.

Answer 1

take a simple problem like

2 numbers have the sum 8 and their difference is 2. Find these 2 numbers

Let the numbers be x and y , so

x + y = 8
x - y = 2
you can then solve this system of equations to find the value of the numbers x and y

Answer 2

Ok...I suck at math and even though your answer is simple and I can understand it, to a degree, I still don't understand.
