Hi,

Important that you learn how to do these:

 

6x-2y=-4     ||Substitute for y and find x ( then y = 5x)



 ||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

 (1)x=1,y=5

(2)x=8/3,y=-8/3

(3)x=-3,y=11

(4)x=1/2,y=-3/2

(5)x=5/2,y=-3/2
