How do solve the following linear system?: # -2x -8y = 4 , 3x-y=3 #?
To solve by elimination you will need to make coefficients of x or y "match" so that when you add or subtract the equations one of the variables will be eliminated.
If we multiply the second equation by 8 we get:
Now if we subtract the two new equations, we will eliminate y and will be able to solve an equation in x.
Substitute this back into one of the original equations to find y.
