how do you solve:::
the sum of two numbers is 3. their difference is 1. find the number.
2 + 1
2 - 1
100,200,300=-576-987=
To solve this problem, we can set up a system of equations based on the information provided.
Let's assume the two numbers are x and y.
From the first statement, "the sum of two numbers is 3," we can write the equation:
x + y = 3
From the second statement, "their difference is 1," we can write the equation:
x - y = 1
Now we have a system of equations:
x + y = 3
x - y = 1
To solve this system, there are various methods, but one common approach is to use the method of elimination.
You can add both equations together, which will eliminate the variable 'y':
(x + y) + (x - y) = 3 + 1
2x = 4
Dividing both sides by 2, we get:
x = 2
Now, substitute the value of x into either equation to solve for y:
2 + y = 3
y = 3 - 2
y = 1
So, the two numbers are x = 2 and y = 1.
