In this method the cross-multiplication technique is used to simplify the solution. Hence it can be easily represented through a coordinate plane on a graph. If not multiply one or both equations by some numbers such that their addition would result in the cancellation of a variable.
Substitute the value found for yinto any equation involving both variables.
This is the more common usage because this is a linear function in slope intercept form - y in terms of x or y dependent on x. A solution of such an. See if adding the equations would result in the cancellation of a variable. A linear equation of two variables can be easily represented algebraically as well as represented geometrically.
