Each worksheet is randomly generated and thus unique. At this point in our study of algebra the use of the properties of equality should seem routine. In other words, think of this as \(56 = +8 + 12y\). Here we can see that the three linear equations are equivalent because they share the same solution set, namely, \(\{7\}\). Lesson plans are editable. Solve and graph the solution set: \(\frac{1}{2}x2\frac{1}{2}(\frac{7}{4}x9)+1\). 6) More than 12.5 weeks. The coefficients of linear equations may be any real number, even decimals and fractions. \(\begin{aligned} 3 x - 12 & = 0 \\ 3 ( \color{Cerulean}{4}\color{Black}{ )} - 12 & = 0 \\ 12 - 12 & = 0 \\ 0 & = 0 \:\:\color{Cerulean}{} \end{aligned}\), Alternatively, when an equation is equal to a constant, we may verify a solution by substituting the value in for the variable and showing that the result is equal to that constant. Isolate the variable term using the addition property of equality, and then multiply both sides of the equation by the reciprocal of the coefficient \(\frac{5}{3}\) . All but one of the rules for solving linear inequalities are the same as solving linear equations. What number would make the inequality \(x>3\) true?
