solve equations with three variables

An equation of one variable and of first order (i.e., its highest power is one) is called a Linear equation. Such an equation has only one solution. A solution is also called the 'root' of the given equation.An equation of one variabl..

Example: A rubber ball dropped from a certain height (h 1 ) on reaching the ground bounces up to a height less than the initial one (h 2 ). It continues to bounce but the height to which it rises keeps decreasing (h 3 , h 4 ). The distance covered by the ball in unit time decreases. The ..

Normally metals donate electrons from their valence shell so as to form positively charged ions such that the charge on the ion is equal to its electropositive valency. However, in transition elements, an atom loses electrons from the shell next to the valence shell (penultimate shell). In such a s..

Solve for the variable in the equation. 2 a = - 6 => - 8 or - 4 or - 3 or 3..

Solve the equation x 3 = 4 2 3 to find the value of the variable x . => 4 2 3 or 14 or 14 9 or 2..

Graphical Method of Solution of a Linear Programming Problem - So far we have learnt how to construct a mathematical model for a linear programming problem. If we can find the values of the decision variables x 1 , x 2 , x 3 , ..... x n , which can optimise (maximize or minimize..

Solve the equation 5 h - 8 b 3 n = 14 e for n , and indicate any restrictions on the values of the variables. => n = 5 h - 8 b 4 2 e , e ≠ 0 or n = 4 2 5 h + 8 b + e , h + b + e ≠ 0 or n = 5 h + 8 b 4 2 or n = 5 h + 4 2..

Let S be a sample space associated with a given random experiment. A real valued function X which assigns to each w i S, a unique real number, X( w i ) = x i is called a random variable . Two types of random variables are 1. Continuous random variableh..
