You cannot solve one equation in three unknowns. You need three independent equations.
Add 2.9 to both sides. y = 8.2
The basic definition of speed is: speed = distance / time Solve this equation for distance, or solve it for time, to get two additional versions of the equation.
A linear equation in three variable.
Select any three values of x in the domain of the equation. Solve the equation at these three points for the other variable, y. Then each (x, y) will be an ordered pair that is a solution of the equation.
You cannot solve one equation in three unknowns. You need three independent equations.
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
Add 2.9 to both sides. y = 8.2
yes
5 -8
To find a, all you have to do is solve 3 X a = 14.4 for a. To do that, simply divide both sides of the equation by 3, which gives you a = 4.8.
5 -8
Solving equations in three unknowns (x, y and z) requires three independent equations. Since you have only one equation there is no solution. The equation can be simplified (slightly) by dividing through by 4 to give: x + 2y + 3z = 11
6 + (4 + n)*3 is an expression, not an equation. An expression cannot be solved since there is no equals sign in it.
It is not appropriate to talk about "the" three solutions for this equations; the equation describes a straight line, and has an infinite number of solutions. Solve the equation for "y", substitute any value for "x", and calculate the corresponding value for "y", to get one opf these solutions.
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
There are three variables in the equation. In order to find numbers for all of them,you need three separate independent equations.As it is now, the graph of that equation is a line in 3-dimensional space, andevery point on the line is a 'solution' to the equation. We don't have to tell youhow many points there are on a line, do we ?
