Hi,
Important that you learn how to do these:
{{{y=5x}}} 
6x-2y=-4     ||Substitute for y and find x ( then y = 5x)

{{{x=8-2y }}} ||Substitute for x and find y (then  x = 8-2y)
4x-y=5 

-7x+y=32    || Multiply 1st EQ by -3 and add to eliminate y (you'll find x =-3
2x+3y=27

2x+y=5      || Multiply 1st EQ by 3 and add to eliminate y  (you'll find x =1/2
4x-3y=-10 

4x+2y=7  
x-5y=10     || Multiply 2nd EQ by -4 and add to eliminate x (you'll find y = -3/2
