When solving a system by multiplying and then adding or subtracting how do you decide whether to add or subtract?
When solving a system of equations by multiplying and then adding or subtracting, you decide whether to add or subtract based on the coefficients of the variables you want to eliminate. If the coefficients of one variable are opposites (e.g., +3 and -3), you would add the equations to eliminate that variable. Conversely, if the coefficients are the same (e.g., +3 and +3), you would subtract one equation from the other to eliminate the variable. The goal is to simplify the system and isolate one variable for easier solving.
What else can I help you with?
What two numbers give you 1242?
It depends on whether you're adding, subtracting, multiplying, etc.
How do you know whether you should add or subtract the value of the two numbers?
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
How is the process of solving an equation like solving inequality?
Solving an equation and solving an inequality both involve finding values that satisfy a mathematical condition. In both cases, you manipulate expressions using similar operations, such as addition, subtraction, multiplication, and division. However, when solving inequalities, you must be cautious with operations that can reverse the inequality symbol, particularly when multiplying or dividing by a negative number. Ultimately, both processes aim to identify a set of values that meet the specified criteria, whether exact (equation) or a range (inequality).
How do you know whether to add or subtract when simplifying expressions?
To determine whether to add or subtract when simplifying expressions, look for operations indicated by parentheses, exponents, and the order of operations (PEMDAS/BODMAS). If you encounter a minus sign in front of a parenthesis, distribute that negative across the terms inside, which may involve both addition and subtraction. Additionally, combine like terms by adding or subtracting coefficients accordingly. Understanding the context and structure of the expression will guide you in applying the correct operations.
When subtracting what to do with the exponents?
It depends on whether you are working with variables. You cannot add terms with variables that have unlike exponents.

Would you add or subtract to negative numbers?
Whatever is required by the context of the question. Whether or not the number is negative gives no indication as to whether to add or subtract.
Why is it important to always subtract the earlier value from the later value when finding the change in mass instead of always subtracting the smaller value from the larger one?
If you always subtract the smaller value from the larger one, the number that you tell other people lets them know how much the mass changed, but it doesn't tell them whether the mass increased or decreased as time passed.
How do you know whether you should add or subtract the value of the two numbers?
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
What is problem solving skills?
Problem solving skills are skills that are needed to solve problems, such as research skills, being able to think and reason clearly, etc.In math, problem solving skills include being able to select whether to use addition, subtraction, multiplication, or division for word problems, knowing how to add, subtract, multiply, and divide, knowing basic theorems, and much more.

What do you not have to think about when you add or subtract fractions?
Whether the denominators are common or not.

What is the difference between the expression x-3 and 3-x?
Well, darling, the difference between x-3 and 3-x is simply the order of subtraction. In x-3, you're subtracting 3 from x, while in 3-x, you're subtracting x from 3. It's like deciding whether you want to take away $3 from your $10 bill or subtract your $10 bill from $3 – either way, you're left with a mess in your wallet.
When subtracting what to do with the exponents?
It depends on whether you are working with variables. You cannot add terms with variables that have unlike exponents.
After you add or subtract two rational expressions its a good idea to see if you can your answer?
You should check whether you can simplify the answer.
What do you do when you're going to subtract fractions but the numerator is the same?
its the same as working with integers. + and a + = + -and a - = + + and a - = - - and a + = - eg. 4/4 - - 3/4= 4/4 + 3/4= 1 3/4 1/2+ - 3/10 = 2/10= 1/5
