Your answer would be ( -12/5 x + 2 )
9x + 1 = 7x - 9
-7x. -7x
2x + 1 = -9
-1. -1
2x = -10
Divide by 2
x = -5
I believe it is A and D. All you have to do is add them all together and if both sides are the same then its a correct answer.
The two numbers are (9+ 5√5)/2 and (9- 5√5)/2.
(9+ 5√5)/2+ (9- 5√5)/2= 9
(9+ 5√5)/2* (9- 5√5)/2= -11
Hope this helps~
