Solving a System of Equations. Systems of linear equations take place when there is more than one related math expression. For example, in \(y = 3x + 7\), there is only one line with all the points on that line representing the solution set for the above equation.
"In Module 4, students use similar triangles learned in Module 3 to explain why the slope of a line is well-defined. Students learn the connection between proportional relationships, lines, and linear equations as they develop ways to represent a line by different equations (y = mx + b, y – y1 = m, etc.). They analyze and solve linear equations and pairs of simultaneous linear equations. The ...
Use substitution and put \(r\) from the middle equation in the other equations. Then, use linear elimination to put those two equations together – we’ll multiply the second by –5 to eliminate the \(l\). We typically have to use two separate pairs of equations to get the three variables down to two!
