Determine which of the following values are solutions to p2 – 2p = 35
          4, -5, -6, 7, 8

Solve for y:                         

 

Solve for g:                            2g + 4h = 16

 

Solve for n:                          -3m + 5n = 30

heres a few more

-5 and 7 are solutions of p^2 - 2p = 35 ( (-5)^2 - 2(-5) = 25 + 10 = 35 and 7^2 - 2*7 = 49 - 14 = 35).

2g + 4h =16; 2g = 16 - 4h; g = 8 - 2h

-3m + 5n = 30; 5n = 3m + 30; n = (3/5)m + 6

PS. Which equation is to be solved for y? Add it and I will do it.
