Yes, addition or subtraction can be used to solve a system of equations, particularly in the method known as elimination. By adding or subtracting equations, you can eliminate one of the variables, making it easier to solve for the other variable. This method is effective when the coefficients of one variable are opposites or can be made to be opposites through multiplication. However, it is not the only method; substitution and graphing are also common approaches.
What else can I help you with?
How would you describe the order of operations to solve any given problem?
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
How do you solve an equation with Multiple operations?
To solve an equation with multiple operations, follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). First, simplify any expressions within parentheses and evaluate any exponents. Then, perform multiplication and division as they appear from left to right, followed by addition and subtraction. Finally, isolate the variable to find the solution.
Use any operation besides addition and subtraction to solve this equation 8 8 8 8 8 equals 9.?
This is not an equation. (8/8) times (8 and 8/8) = 9
What is the rules in PEMDAS?
PEMDAS is an acronym that helps remember the order of operations in mathematics: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). According to these rules, you first solve expressions within parentheses, then handle exponents, followed by any multiplication or division, and finally, perform addition and subtraction. This order ensures that mathematical expressions are evaluated consistently and accurately.
What is the zero property of subtraction?
The zero property of subtraction states that subtracting zero from any number does not change the value of that number. In mathematical terms, for any number ( a ), the equation ( a - 0 = a ) holds true. This property highlights that zero acts as an identity element in subtraction, similar to its role in addition.

Is it true that Excel completes addition and subtraction?
Excel can do any kind of mathematical operation, so that includes addition and subtraction.
Why is it we don't have any properties of subtraction and division?
Because subtraction is addition and division is multiplication. So, subtraction would fall under the properties of addition and division would come under the properties of multiplication.

What is an arithmetic operation?
The basic arithmetic operations are addition, subtraction, multiplication and division, although this subject also includes more advanced operations, such as manipulations of percentages, square roots, exponentiation, and logarithmic functions.

When finding the value of an expression should you always complete any addition before subtraction?
No, addition and subtraction are performed in any order. Consider 6 + 3 - 2. You can do it two ways:6 + 3 -1 = 9- 1 = 8, or 6 + 3 -1 = 6 + 2 = 8.

Is how many addition or subtraction?
"How many ?" is counting. It can be the result of any math operation.In fact, "How many ?" is the question at the end of EVERY math problem. Whateverthe problem is, it always says "After you do this, how many do you wind up with ?"

What is bomdas rule?
The BOMDAS rule is the order in which processes in a mathematical operation must be performed. It stands for Brackets - solve the parts in any brackets before doing anything else. Ordinals - work out any square, cube or other powers, Multiplication and Division - these must be done before.... Addition and Subtraction.
