Sure, here are some step by step solutions: Example Problem: Solve for x: 2x + 5 = 13 Step 1: Subtract 5 from both sides of the equation $\begin{array}{rl}2x+5-5& =13-5\\ 2x& =8\end{array}$ Step 2: Divide both sides of the equation by 2 $\begin{array}{rl}\frac{2x}{2}& =\frac{8}{2}\\ x& =4\end{array}$ Therefore, the solution to the equation 2x + 5 = 13 is x = 4. Example Problem: Find the slope-intercept form of the equation of the line passing through the points (2, 3) and (4, 5) Step 1: Find the slope using the formula: m = (y2 - y1) / (x2 - x1) $\begin{array}{rl}m& =(5-3)/(4-2)\\ m& =2/2\\ m& =1\end{array}$ Step 2: Use the point-slope form of the equation of a line to find the equation: y - y1 = m(x - x1) $\begin{array}{rl}y-3& =1(x-2)\\ y-3& =x-2\\ y& =x+1\end{array}$ Therefore, the equation of the line passing through the points (2, 3) and (4, 5) in slope-intercept form is y = x + 1.
