## What is the rule for adding and subtracting algebraic terms?

To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same. To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same. on the variables the same.

## How do you add and subtract algebra?

## How do you subtract equations with variables?

You can isolate one variable in one equation, then substitute it in the second equation. Or you can manipulate one of the equations so that you have equal values of one variable, then subtract one equation from the other, eliminating the variable.

## What are the steps to solving a linear equation?

Step 1: Simplify each side, if needed.Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.Step 3: Use Mult./Div. Step 4: Check your answer.I find this is the quickest and easiest way to approach linear equations.Example 6: Solve for the variable.

## How do you solve linear equations examples?

Solving Linear EquationsSolve: (2x + 5)/(x + 4) = 1. ⇒ 2x – x = 4 – 5 (Transferring positive x to the left hand side changes to negative x and again, positive 5 changes to negative 5) Solution: ⇒ 3x/3 = 9/3 (Dividing both sides by 3) ⇒ 5 – 2x + 2 = 12 – 4x – 2x (Removing the brackets and then simplify) x/2 + x/3 = x – 7.

## When adding and subtracting expressions do you combine?

Only the coefficients of like terms are different. Since adding or subtracting unlike terms is like mixing apples and oranges — only like terms can be combined. To combine like terms, add the coefficients and multiply the sum by the common variables. Click on the apples to group the like terms in the expression.

## What are the five rules of exponents?

Exponents product rules. Product rule with same base. an ⋅ am = an+m Example: 23 ⋅ 24 = 23+4 = 27 = 2⋅2⋅2⋅2⋅2⋅2⋅2 = 128. Exponents quotient rules. Quotient rule with same base. an / am = anm Example: 25 / 23 = 253 = 22 = 2⋅2 = 4. Exponents power rules. Power rule I. (an) m = a nm Example:

## What are the 4 steps to solving an equation?

We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal.

## How do you add or subtract fractions with variables?

The steps we follow to subtract fractions with variables are as follows.Find a common denominator by multiplying the two denominators together.Manipulate the fractions so that they both have the common denominator.Once you have a common denominator in both fractions, subtract the numerators.
