<> Given a linear equation in the form \(ax + b = cx + d\), we begin the solving process by combining like terms on opposite sides of the equal sign. 8 = 16 + n 3. Topics covered: Solve multi-step linear equations and inequalities with various methods Writing and solving equations/inequalities from word problems/real-life scenarios See sample questions above! Step 2: Use the appropriate properties of equality to combine like terms on opposite sides of the equal sign. As indicated, you should expect \(x=0\) to solve the original inequality and that \(x=5\) should not. Inequalities typically have infinitely many solutions. Step 1: Simplify both sides of the equation using the order of operations and combine all like terms on the same side of the equal sign. Size of the graph images (in pixels): Choose the types of problems for the worksheet.
