explain in complete sentences how you would use the elimination method to solve the following system of equations and provide the solution to the system .

5x-3y=4
3x-5y=-4

anonymous · Answer

1)add two equations
2)subtract the two equations
then just use the normal method

anonymous · Answer

this is harder then i thought :P

anonymous · Answer

To eliminate y first, multiply the first equation by five, and the second by -3.
$$5((5x-3y)=4)$$
$$-3((3x-5y)=-4)$$
you would then get...
$$25x-15y=20$$ 
$$9x+15y=12$$
subtract, and you get...
$$34x=32$$
so, x=16/17

to find y, do the same thing, but just cancel the x-terms. OR, substitute x=16/17 in one of the equations.
in the end, $$y=2$$

hope this helps, let me know if you have any more questions!
