Answer 11

However many you feel comfortable helping me with out of those 3 would be greatly appreciated PLEASE and THANK YOU.. "any of them" would be appreciated

Answer 12

For number 8 muliply x +6y=2 by -5 both sides, then add both eq's like before. X's will cancel then solve for y. Back substitute y you find into a formula and solve for x.

Answer 13

For number 9 put the y eq. in for the y in the other eq.
So 3x - (2x - 1) = -1 solve for x then back sub for y

Answer 14

Problem 9 is pretty much the same as 8 (;
