In addition to being easy to use, the linear equations and inequalities worksheets have answer manuals that contain the solutions to all problems given in the sheet. In summary, to retain equivalent equations, we must perform the same operation on both sides of the equation. You may add or subtract any real number to both sides of an inequality, and you may multiply or divide both sides by any positive real number to create equivalent inequalities. Solve each inequality. Figure \(\PageIndex{2}\) shows both the number line and the interval notation. Here we can see that the three linear equations are equivalent because they share the same solution set, namely, \(\{7\}\). Solve linear equations and linear inequalities in one variable, including equations with coefficients represented by letters (literal that are linear in the variables being solved for). Students begin their study of algebra in Books 1-4 using only integers.
