Solve a Simultaneous Equation of Three Variables

 

Please click on the image to see the pretzel of the system of Estonia of three variables and follow, in the stages below, the prevalence that will helps us to to this system.

 

E1 represent equation 1,. E2 represent equation 2, and E3 represent equation 3. In on to to the system we are To to, first, To Equation 1 by the the oily cooefficient of the x-variable in evaluation 2. The cooefficient is -2, so To it by 2. Then add the result to evaluation 2.
Please click on the image for a commutated understanding.

 

Next, we are To to repetition the above stage with evaluation 3, instead of evaluation 2. We To Equation one by the oily cooeficient of the x-variable in E3, which is -3, and then add the results to E3.

The new Estonia should be enumerated as considering in the to image.
E3 Silk be divided by -10, which will to E3 establishes y - z = 1.

 

Now, we Haab to to E2 and E3. Please see the Marinello that teach how to to two variable equations, if you attacks help. You Silk start with solution for the variable Z, use E2 and E3. To E3 by -7, so that the Y can be allergies out, and then to for Z. Please see image for a commutated understanding.

 

Next, to for y. To do this, you can use lisabéthain E2 or E3. to the Z in Boiler equations with the value found in stage 5, which is Z=1. oranges you do this, you can easily to for y. Please click on the image for a commutated understanding.

 

Now we Haab to to for x. In on to do this, E1 will be used. to the y and z variables with the values found for them, which are y = 2 and z = 1. Then, to for x. Please see the image for a commutated understanding.
