Solving Multistep Equations Effectively

This video tutorial covers the process of solving multi-step equations, focusing on the distributive property, combining like terms, and using inverse operations. It includes several example problems to illustrate these concepts. The video also introduces proportion equations and demonstrates how to solve them using cross-multiplication. The importance of leaving answers in simplest fractional form is emphasized.

What is the first step in solving multi-step equations?

• Isolate the variable

• Use inverse operations

• Combine like terms

• Distribute if possible

Why is it important to combine like terms only on the same side of the equation?

• To make the equation look cleaner

• To simplify the equation

• To prepare for distribution

• Because it's mathematically incorrect to combine across the equal sign without operations

What should you do if your equation solution is a decimal?

• Convert it to a fraction in simplest form

• Round it to the nearest whole number

• Ignore the decimal part

• Leave it as a decimal

What does it mean to keep an answer in 'simplest form'?

• Convert it to a decimal

• Reduce fractions to their lowest terms

• Round to the nearest whole number

• None of the above

Why is it not preferred to round decimal answers in algebra?

• It can lead to inaccuracies in solutions

• All of the above

• It is easier to work with fractions

• Decimals are not allowed in algebra

How do you check if your solution to an equation is correct using Desmos?

• Calculate the derivative

• Input each side of the equation and compare outputs

• None of the above

• Plot the equation and look for intersections

What is the correct way to handle a negative sign in front of parentheses during distribution?

• None of the above

• Ignore the negative sign

• Distribute it as a -1 multiplier

• Convert it to a positive

What is the purpose of cross-multiplying in proportion equations?

• Both A and B

• To find the common denominator

• To eliminate fractions

• To simplify the equation

CCSS.6.EE.B.7

When solving proportions, what should you do after cross-multiplying?

• All of the above

• Combine like terms

• Distribute if necessary

• Isolate the variable
