How do you solve the following system: # -6x + 5y = 4 , x-10y=10 #?
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 double the first equation we get:
#-12x + 10y = 8#
#x - 10y = 10#
Now if we add 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.
