Three by three systems of linear equations are also used to solve real-life problems. The given problem is expressed as a system of linear equations and then solved to determine the value of the variables. Sometimes, the system will consist of three equations but not every equation will have three variables. Example three is one such problem.

b. Use your equation to find the cost of a 30-minute call. More Word Problems in Point-slope form. Sometimes instead of giving a rate, a word problem gives two relationships at different points in time between variables. This kind of problem is giving you two points. You must find the slope and then use one of the points to write an equation. 1.

Use substitution to solve the system of equations. If the system does not have one solution tell whether it has infinitely many solutions or no solution. Y = 2x + 1. 2y = 4x +2. Step 1 - Choose a variable to solve for. Look for the easiest way to solve the problem. Because the first equation is already solved for y I will choose the first equation.

In all vector problems a natural system of axes presents itself. In many cases the axes are at right angles to one another. Components parallel to the axes of a rectangular system of axes are called rectangular components. In general it is convenient to call the horizontal axis X and the vertical axis Y.
