what is the answer to these simultaneous equations?
2x + y = 8 5x + 3y = 12 y = -2x + 8 5x + 3(-2x + 8) = 12 5x - 6x + 24 = 12 -x = -12 x = 12 y = -2(12) + 8 y = -24 + 8 y = -16 ANS : (12,-16) --------------------------------------- 2x + 3y = 12 5x + y = 14 y = -5x + 14 2x + 3(-5x + 14) = 12... Read More »

How to Use Simultaneous Equations
In any algebraic system of equations, the number of variables that can be solved for is dependent on the number of equations. One variable (most often X) requires at least one equation; solving for three variables (X, Y and Z) requires at l... Read More »

How to Graph Simultaneous Equations
An equation yields a set of x and y coordinates that, when plotted on a Cartesian Coordinate Plane, produces a particular graph. When two or more linear equations are plotted on the same plane, they are known as simultaneous equations. It i... Read More »

Simultaneous equations are systems or sets of multiple equations that contain multiple variables. The equations in the set are related to one another by a set of joint conditions imposed on the variables. There is only one unique solution o...

Systems of simultaneous linear equations are solved mechanically through the use of a method called Gauss elimination. This method uses a matrix formed by the constant coefficients in the equations augmented by the vector formed by the equa...

There are three ways to solve this problem, graphing, substitution or elimination. Graphing is tough in a computer and without a calculator. Substitution works fine here but elimination is even easier. Add the two equations together: (2x + ...

2xy = 1/3 3x = y Where you see a 'y' in the first equation, substitute in '3x' Hence 2xy = 1/3 2x(3x) = 1/3 Multiply 2x & 3x together, which is 6x^2 Hence 6x^2 = 1/3Divide through by '6' x^2 = 1/18 x = sqrt(1/18) x^2 + y^2 + 2x = 17 y-x = 7...
