Solving multi-step inequalities Video transcript Let's do a few more problems that bring together the concepts that we learned in the last two videos. So let's say we have the inequality 4x plus 3 is less than negative 1. So let's find all of the x's that satisfy this. So the first thing I'd like to do is get rid of this 3.
Easy to understand explanations on solving two-step algebra equations. Now that you know all the rules for solving one-step equations, solving two-step algebra equations will be a piece of cake! You will need prior knowledge of solving one-step equations in order to understand this lesson.
There are 5 examples to this lesson, so make sure that you keep scrolling down to learn how to solve all types of two step equations. You'll even find a couple of video lessons to help guide you through this process. Each equation is going to be solved in two separate steps. Let's take a look: Therefore, this equation will involve two separate steps.
Remember that you must use the opposite mathematical operation in order to remove a number from one side of an equation.
There's one rule to remember when solving two-step equations: Tips for Solving Two-step Equations Always remove the constant first using addition or subtraction. Your second step will be to remove any coefficients or divisors using multiplication or division.
Let's solve this example together. Notice how two separate steps are involved in solving this equation. Example 1 - Two-step Equation Just in case you are still confused, we'll look at another example similar to this one. Remember to focus on how there are two steps that are used in order to find the solution to this equation.
Not only can you watch video lessons, you will have access to the practice worksheets, answer keys, quizzes and tests!
The next two examples will demonstrate how to solve two-step equations when the coefficient is a fraction or when you have a divisor. Let's take a look! Example 3 - Two-step Equations with a fraction I know you are feeling pretty good about this, but let's keep going!
More Two-step Equations Ok This example involves an additional step before starting the two-step process. If you have any terms in the equation that are like terms, then you will want to combine those like terms first before solving.
Let's take a look You just applied two different rules for solving equations in order to solve two-step equations. I know you are feeling better now! Having Trouble with Your Homework?

Hi Brent, thank you for the very useful videos. Could you please help with the following problem from GMAT official guide: How many of the integers that satisfy the inequality (x+1)(x+3)/(x-2)≥ 0 .
LAWS OF EXPONENTS - To multiply powers of the same base, add their exponents. Thus, 2 2 times 2 3 = 2 5 = 32 PROOF: 2 2 = 4; 2 3 = 8; 2 5 Therefore; 4 x 8 = 32 To divide powers of the same base, subtract the exponent of the divisor from the exponent of the dividend.
