Step 1: Solve one of the equations for one variable. Step 2: Substitute this in the other equation to get an equation in terms of a single variable. Step 3: Solve it for the variable. Step 4: Substitute it in any of the equations to get the value of another variable.

The x value of the point (x, y) is known as the abscissa. It represents the distance of the point from the origin or along the horizontal x-axis. The y value of the point (x, y) is known as the ordinate. It represents the vertical or perpendicular distance of the point from the origin or from the x-axis.

A function defines one variable in terms of another. The statement "y is a function of x" (denoted y = y(x)) means that y varies ing to whatever value x takes on.

How To: Given a system of two equations in two variables, solve using the substitution method. Solve one of the two equations for one of the variables in terms of the other. Substitute the expression for this variable into the second equation, then solve for the remaining variable.

One method is by using inverse operations. This means that you can use addition and subtraction to solve for x if the equation includes multiplication or division. For example, if you have the equation 4x=12, you can divide both sides by 4 to get x=3. Another method for solving for x is by using factoring.

The basic rule for solving multi-variable, multi-step equations is to first be sure you have the same number of equations as the number of different variables in the equations. Then, solve one of the equations for one of the variables and plug that expression in for what it equals into the other equation.

If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r.

In mathematics, x is commonly used as the name for an independent variable or unknown value. The modern tradition of using x, y and z to represent an unknown (incognita) was introduced by René Descartes in La Géométrie (1637).

A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

The slope-intercept form of a linear equation is y = mx + b. In the equation, x and y are the variables. The numbers m and b give the slope of the line (m) and the value of y when x is 0 (b). The value of y when x is 0 is called the y-intercept because (0,y) is the point at which the line crosses the y-axis.
