Use the multiplication property of equality to solve each of the following equations. In each case, show all the steps. $$7 x=-35$$

Solve each equation using the methods shown in this section. $$2(3 x-6)+1=7$$

Simplify the following expressions by combining similar terms. In some cases the order of the terms must be rearranged first by using the commutative property. $$-2 a+a+7+5$$

Solve each equation. $$x-8=-3$$

Find three solutions to each of the equations and use them to draw the graph. (GRAPH CANT COPY) $$x-y=4$$

For each of the following equations, complete the given table. $$x+y=5$$ $$\begin{array}{l|l} \hline x & y \\ \hline 2 & \\ \hline 3 & \\ \hline & 4 \\ \hline & \\ \hline \end{array}$$

Find three solutions to each of the equations and use them to draw the graph. (GRAPH CANT COPY) $$x-y=5$$

We have mentioned the two temperature scales, Fahrenheit and Celsius. Table 1 is intended to give you a more intuitive idea of the relationship between the two temperatures scales. (TABLE CANNOT COPY) Table 2 gives the formulas, in both symbols and words, that are used to convert between the two scales. (TABLE CANNOT COPY) Let \(C=100\) in the formula \(F=\frac{9}{5} C+32,\) and solve for \(F\) Does the value of \(F\) agree with the information in Table \(1 ?\)

Solve each equation. $$y-5=-1$$

Use the six steps in the 鈥淏lueprint for Problem Solving鈥� to solve the following word problems. You may recognize the solution to some of them by just reading the problem. In all cases, be sure to assign a variable and write the equation used to describe the problem. Write your answer using a complete sentence. If the sum of three times a number and two times the same number is increased by 1, the result is 16 . Find the number.
