# Lagrange multiplier
A Lagrange multiplier is a constant, usually represented by the Greek symbol lambda (λ), which is part of the formula for finding an extreme value of a function f(x,y) subject to a constraint g(x,y). For example, the method of Lagrange multipliers can help determine the maximum area of a rectangl... |
# How do you solve the following linear system: 4x+3y=8 , x-2y=13 ?
Jan 28, 2016
$\left(x , y\right) = \left(5 , - 4\right)$
#### Explanation:
$4 x + 3 y = 8$
$x - 2 y = 13$
In the second equation we can find the value of $x$ by transposing $2 y$ to the other side of the equation and we can substitute the value o... |

Therefore, if $a<0$ , then the range is $\left(-\infty ,q\right)$ , meaning that $f\left(x\right)$ can be any real number less than $q$ . Equivalently, one could write that the range is $\left\{y\in \mathbb{R}:y .
For example, the domain of $g\left(x\rig... |
