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.

yes

Add 2.9 to both sides. y = 8.2

5 -8

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.

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

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.

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.

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.
