Weegy: Writing Systems of Linear Equations from Word Problems Some word problems require the use of systems of linear equations. [ Here are clues to know when a word problem requires you to write a system of linear equations: (i) There are two different quantities involved: for instance, the number of adults and the number of children, the number of large boxes and the number of small boxes, etc. (ii) There is a value associated with each quantity: for instance, the price of an adult ticket or a children's ticket, or the number of items in a large box as opposed to a small box. Such problems often require you to write two different linear equations in two variables. Typically, one equation will relate the number of quantities (people or boxes) and the other equation will relate the values (price of tickets or number of items in the boxes). Here are some steps to follow: 1. Understand the problem. Understand all the words used in stating the problem. Understand what you are asked to find. Familiarize the problem situation. 2. Translate the problem to an equation. Assign a variable (or variables) to represent the unknown. Clearly state what the variable represents. 3. Carry out the plan and solve the problem. Use substitution, elimination or graphing method to solve the problem. source: ]
