I get twenty-five" can be translated into an algebraic equation. Let's represent the unknown number with the variable 'x'. Doubling the number is represented as 2x. Adding eleven to the doubled number results in 2x + 11. The statement indicates that this expression equals twenty-five. Therefore, the equation is: 2x + 11 = 25 The answer is: **2x + 11 = 25** ☆**Question b:** **Solve the equation 2x + 11 = 25** Step 1: **Isolate the term with the variable 'x'.** Subtract 11 from both sides of the equation: 2x + 11 - 11 = 25 - 11 2x = 14 Step 2: **Solve for 'x'.** Divide both sides of the equation by 2: x = 14/2 x = 7 The answer is: **7** Click to rate:92.4(1037 votes)Search questionBy textBy image/screenshotDrop your file here orClick Hereto upload
