The solution of a linear inequality in two variables like Ax By C is an ordered pair x y that produces a true statement when the values of x and y are substituted into the inequality. Linear Equations in Two Variables Definition and Solutions A Linear equation in two variables is represented in the form of axbyc 0 where ab c are real numbers and coefficients a b are not equal to zero. The equation we solve and the variable we solve for technically doesnt matter as noted above.
In this case we can quickly solve the first equation for x without a lot of extra work so lets do that.
In this case the equation can be put in the form and it has a unique solution in the general case where a 0In this case the name unknown is sensibly given to the variable x. Skill Summary Legend Opens a modal Solutions of a linear equation. However there is often one equationvariable combination that is easier than the others.
