subtracting 395 from 1st eqn __ -11x-395=y

substituting into 2nd eqn __ 14(-11x-395)=-634-10x __ -154x-5530=-634-10x

-144x=4896 __ x=-34

substituting __ -11(-34)-395=y __ -21=y

-11x = 395 + y
14y = -634 - 10x
:
Any method is tedious here, arrange the equations, thusly:
-11x - y = 395
+10x +14y = -634
:
Multiply the 1st equation by 14
-154x - 14y = 5530
+ 10x + 14y = -634
---------------------addition eliminates y, find x
-144x + 0y = 4896
x = 4896%2F%28-144%29
x = -34
:
Find y using the 2nd original equation
14y = -634 - 10(-34)
14y = -634 + 340
14y = -294
y = %28-294%29%2F14
y = -21

:
Check solutions in the 1st original equation:
-11x = 395 + y
-11(-34) = 395 + (-21)
+374 = 395 - 21
374 = 374; equality reigns
