I dont see any equations.
But to solve by the elimination method you have to make one variable eliminated. Ill show an example. Im not an expert so the varaible will probably not come out as whole numbers.
4x+6y=18
7x+y=24
To eliminated one o the variables multiply by the proper number to the whole equation. Multiply the bottom euqations by -6
4x+6y=18
-42x-6y=-144
Now add the equations top down...
-38x = -126
x = -126/-38
x = 3.315
Now solve for y by plugging x into one of the euqations.
4(3.315)+6y=18
y=0.2262
As I said before im not an expert and these answers are ugly. But this is how you do it. Make sure you take your time and dont make dumb mistakes like simple adding or subtracting mistakes.
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.
By elimination: x = 3 and y = 0

You can solve the system of equations with three variables using the substitute method, or using matrix operations.
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.
Simultaneous equations can be solved using the elimination method.
Multiply every term in both equations by any number that is not 0 or 1, and has not been posted in our discussion already. Then solve the new system you have created using elimination or substitution method:6x + 9y = -310x - 6y = 58
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.

You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.

You use algebra and solve the system(s) of equations using techniques such as elimination or substitution.
Elimination is particularly easy when one of the coefficients is one, or the equation can be divided by a number to reduce a coefficient to one. This makes substitution and elimination more trivial.
You cannot solve one linear equation in two variables. You need two equations that are independent.
