If two variables are related by a single first-degree equation, there are infinitely many ordered pairs that are solutions of the equation. When the variables are a and b, the ordered pair is given in the form a, b.
If the graphs of algebar equations in a system do not intersect-that is, if the lines are parallel see Figure 8. As in the above example, the solution of a system of linear equations can be a single ordered pair.
In the above example, it was easy to express y dalculator in terms of x using Equation 1. Then, we represent the word phrases in terms of two variables.
Thus, Equation 4' is equivalent to Equation 4.
Solve quadratic equations, solve higher degree equations, solve equations with roots with our free step-by-step algebra solver. In the above example, we were able to obtain an equation in one variable by adding Equations (1) and (2) because the terms +y and -y are the negatives of each other. Sometimes, it is.– Bruce, Anaheim, CA
