How to solve elimination

Elimination is a method of solving a system of linear equations. To solve a system of equations using elimination, you need to add or subtract the equations so that one of the variables is eliminated.

For example, if you have two equations:

2x + 3y = 8
4x + 6y = 16

You can add the two equations together to eliminate the y variable:

2x + 3y = 8
+4x + 6y = 16
___________
6x + 9y = 24

Now you can solve for x:

6x + 9y = 24
-9y = -24
6x = 24
x = 4

Once you have solved for x, you can substitute it into either of the original equations to solve for y:

2x + 3y = 8
2(4) + 3y = 8
8 + 3y = 8
3y = 0
y = 0

Therefore, the solution to the system of equations is x = 4 and y = 0.

How to solve
5d=2e-14
5e=d+12

double the 2nd equation to get
5d=2e-14
10d=2e+24
now subtract 1st from 2nd to get
5d=12
and it's all easy from here on ... right?
