Question 123558
The given expression is: 


8x = -2y - 10  ---------------------(1)


2x = 4y -------------------(2)


This can be written as {{{  x = (4y/2) }}}


==> x = 2y --------------(3) 


Substituting (3) in (1) we get: 


8(2y) = - 2y - 10 


16y = - 2y - 10


16y + 2y = -10 


18y = -10 


y = -{{{(10/18)}}}


==> y = - 5/9 


By back substitution we can find the value of "x". 



x = 2y 


x = {{{2(- 5/9)}}}


x = - 10/9 


Thus the solution.
