Let X be one number and Y the other. So, X + Y = 8 and X - Y = 12 Solve the set of equations simultaneously or use substitution method. X + Y = 8 X - Y = 12 (ADD THIS EQUATION TO FIRST ONE) _______________ 2X = 20, So X =10 and solving for Y using either equation, Y = -2

What is the difference between subtraction and addition?
Subtraction involves taking away a number from another number, while addition involves combining two or more numbers to find a total sum. Subtraction results in a smaller number, while addition results in a larger number.
Find two whole numbers whose sum is 166 and difference is 32?
Let x be one of the numbers. Then the other number is 166 - x. Given that their difference is 32, we can set up the equation x - (166 - x) = 32 and solve for x. This yields x = 99 and 166 - x = 67. So, the two whole numbers are 99 and 67.
If the sum of two numbers is 6 and there difference is -2 what are the two numbers?
Let numbers be x and y. Then, x + y = 6 x - y = -2 add up both equations 2x + y - y = 6 + (-2) 2x = 4 divide by 2 to both sides x = 2 Since the sum of the numbers is 6 and one of the numbers is 2, then the other number is 4 (6 - 2). Check: 2 + 4 = 6 2 - 4 = -2
What is Ashanti number?
An Ashanti number is a concept in mathematics related to the Fibonacci sequence, where each term is the sum of the two preceding ones. Ashanti numbers are formed by starting with two initial values and then generating subsequent terms based on their sum. This concept can be extended beyond Fibonacci numbers to include other sequences derived in a similar manner.
What are the types of Addition?
The types of addition include associative (changing the grouping of numbers does not change the sum), commutative (changing the order of numbers does not change the sum), and identity (adding zero to a number gives the same number).
