Question 516182: I am trying to solve the system of equations for the following set:
{ 4/5x + y = 14/5 and -1/8x - 1/4y = -1 }
I cannot get the right answer because I keep factoring incorrectly when I multiply by the LCM.
Please provide the ordered pair.
Thanks.

multiplying 2nd eqn by 4 ___ -1/2 x - y = -4

adding 1st eqn (to eliminate y) ___ 3/10 x = -6/5 ___ x = -4

-1/2 (-4) - y = -4 ___ 2 - y = -4 ___ y = 6
