by elimination,substitution or through the matrix method.
Solve the following systems of simultaneous linear equations using Gauss elimination method and Gauss-Seidel Method 2x1+3x2+7x3 = 12 -----(1) x1-4x2+5x3 = 2 -----(2) 4x1+5x2-12x3= -3 ----(3) Answer: I'm not here to answer your university/college assignment questions. Please refer to the related question below and use the algorithm, which you should have in your notes anyway, to do the work yourself.
If you mean: x = 8y+5 and 3x-2y = 11 then the simultaneous equations can be solved by a process of elimination. -------------------- Since the first equation is solved for x, substitution should be easy. There is no "right" answer to this question - it depends on your taste and experience.
Yes
Yes, for solving simultaneous equations.
Simultaneous equations can be solved using the elimination method.
The elimination method only works with simultaneous equations, hence another equation is needed here for it to be solvable.
The elimination method and the substitutionmethod.
by elimination,substitution or through the matrix method.
True
Simultaneous Equations are very helpful because it can help u solve problems in real life. There are 2 ways to approach a simultaneous equation, Substitution and elimination method. As a good practice it is always good to practice your substitution method first. I wont go too advance for now but consider this question; Find two numbers whose sum is 21 and difference is 9. This question requires 2 equation to solve; thus it is call simultaneous equation. Solve: Let x be a number, and Let y be another number. x + y = 21 equation 1 x - y = 9 equation 2 Rearrange equation 2 to make equation 3(Equation 3 is just to sub into the other eqs) x = 9 + y equation 3 Sub equation 3 into 1 (9 + y) + y = 21 9 + 2y = 21 2y = 12 y = 6 First solution! Sub y = 6 into equation 2 x - 6 = 9 x = 15 Second Solution! Therefore, the numbers are 15 and 6. In a simultaneous equation (with 2 variable) there will always be 2 answers. Good luck and hope this help.

I do not really understand your question. If you have a simultaneous equation that you can't solve. Post it up and i will help.* * * * *Good answer, but spoiled by the last-but-one paragraph. Simultaneous linear equations with two variables can have no solutions (if the corresponding graphs are distinct parallel lines) or infinitely many solutions (if they are, in effect, the same line). And then, there are always simultaneous non-linear equations. Two quadratics, for example, can have 0, 1, 2 or infinitely many solutions.
