WebCombining like terms yields. x - 2 = 10. Adding 2 to each member yields. x-2+2 =10+2. x = 12. To solve an equation, we use the addition-subtraction property to transform a given equation to an equivalent equation of the form x = a, from which we can find the solution by inspection. Example 3 Solve 2x + 1 = x - 2. Webx − 3 x − 7 > 0 x - 3 x - 7 > 0. Find all the values where the expression switches from negative to positive by setting each factor equal to 0 0 and solving. x−3 = 0 x - 3 = 0. x−7 = 0 x - 7 = 0. Add 3 3 to both sides of the equation. x = 3 x = 3. Add 7 7 to both sides of the equation. x = 7 x = 7. WebNow an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it.
