Sure, here are some step-by-step solutions: 1. To solve an algebraic equation, begin by isolating the variable on one side of the equation. Example: Solve for x in the equation 2x + 5 = 13. $\begin{array}{rl}2x+5& =13\\ 2x& =8\\ x& =4\end{array}$ 2. If an equation involves fractions, get rid of the fractions by multiplying both sides of the equation by the least common denominator. Example: Solve for x in the equation $\frac{x}{3}+\frac{x}{2}=5$. $\begin{array}{rl}\frac{x}{3}+\frac{x}{2}& =5\\ \frac{2x}{6}+\frac{3x}{6}& =5\\ \frac{5x}{6}& =5\\ x& =6\end{array}$ 3. When solving a quadratic equation, use the quadratic formula or factor the equation to find the roots. Example: Solve for x in the equation $x^2+6x+5=0$. $\begin{array}{rl}{x}^2+6x+5& =0\\ (x+1)(x+5)& =0\\ x& =-1\text{ or }-5\end{array}$ 4. When solving a word problem, read the problem carefully and define variables. Then, use algebraic equations to represent the relationships between the variables. Example: A rectangle has a perimeter of 22 meters. If the length of the rectangle is 4 meters longer than its width, what are the dimensions of the rectangle? $\begin{array}{rl}2l+2w& =22\\ l& =w+4\\ 2(w+4)+2w& =22\\ 4w& =14\\ w& =\frac{7}{2}\\ l& =\frac{15}{2}\end{array}$ 5. When graphing linear equations, use the slope-intercept form $y=mx+b$, where m is the slope and b is the y-intercept. Example: Graph the equation $y=2x+3$. - Plot the y-intercept at (0,3). - Use the slope to find another point. Since the slope is 2, move up 2 units and right 1 unit from (0,3) to get (1,5). - Draw a line through the two points to graph the equation. I hope these step-by-step solutions help!
