In summary, the first step in solving an equation is to simplify both sides by combining like terms and using the distributive property if necessary. The basic rules for solving equations include adding or subtracting the same number to both sides, multiplying or dividing both sides by the same number, and isolating the variable on one side of the equals sign. You need to use the inverse operation when there is a variable being added or subtracted to a number. The difference between an equation and an expression is that an equation shows that two expressions are equal, while an expression is a combination of numbers, variables, and operations without an equals sign. If you are having trouble solving an equation, you can seek help from a teacher, tutor, or classmate

What is the first step in solving an equation?

The first step in solving an equation is to simplify both sides of the equation by combining like terms and using the distributive property if necessary.

What are the basic rules for solving equations?

The basic rules for solving equations include adding or subtracting the same number to both sides, multiplying or dividing both sides by the same number, and isolating the variable on one side of the equals sign.

When do you need to use the inverse operation in solving equations?

You need to use the inverse operation when there is a variable being added or subtracted to a number. In this case, you would use the opposite operation (subtraction or addition) to isolate the variable.

What is the difference between an equation and an expression?

An equation is a mathematical statement that shows that two expressions are equal, whereas an expression is a combination of numbers, variables, and operations. An equation contains an equals sign, while an expression does not have an equals sign.

What should you do if you are having trouble solving an equation?

If you are having trouble solving an equation, you can seek help from a teacher, tutor, or classmate. You can also try breaking the equation down into smaller steps or using online resources for extra practice and explanations.
