Guided student notes for Intermediate AlgebraTeacher notes (student notes with answers)Presentations in Keynote for Apple Products and PDFExamples are from the OpenStax free courseware textbook. I use this as a study guide for STAAR and as a review for students if they have to retest in class over this unit. These grade 7 math worksheets follow a step-wise pattern so that students can easily explore all the topics in detail. When solving linear equations, the goal is to determine what value, if any, will produce a true statement when substituted in the original equation. \(\begin{align*} - 10 a + 5 &= -25 \\ - 10 ( \color{Cerulean}{2} \color{Black}{ ) +} 5 & = -25 \\ -20 + 5 & = -25 \\ -15 &\neq 25\:\: \color{red}{}\end{align*}\).

Recall that when evaluating expressions, it is a good practice to first replace all variables with parentheses, and then substitute the appropriate values. Solving Compound Inequalities Transform each compound inequality into two linear inequalities and solve them independently by isolating the variable.

Alternatively, we can multiply both sides of \(a=2\) by negative one and achieve the same result. Students will practice translating and solving two-step inequalities from real world situations. \\ - 5 a + 2 = 1 & \quad\color{Cerulean} { Subtract\: 2\: on\: both\: sides.} Simplify the linear expressions on either side of the equal sign first. In this sense, we say that solutions satisfy the equation.. We can express this solution in two ways: using set notation and interval notation. This unit is a bundle of these concepts and will require very little time for the teacher to prepare since everything is provided for you. Solve linear inequalities and express the solutions graphically on a number line and in interval notation. . Next, isolate the variable using the equality property of multiplication or division. 10 &>-5\\[4pt] To solve a math equation, you need to find the value of the variable that makes the equation true.
