Answer:

-21y + 85

Step-by-step explanation:

8x - 5y + 37

x = 2y + 6

place the second equation of x with the first equation

8( 2y + 6 ) - 5y + 37

then simplify

16y + 48 - 5y + 37

48 - 21y + 37

-21y + 85

but if the first equation changed the symbol at the end the answer would be

y = 11/21
