Step-by-step explanation:

collect liked terms:

x+2a=12+ax-6a

2a-ax+6a=12-x

a(2-x+6)=12-x

divide both sides by (2-x+6) :

a(2-x+6)/(2-x+6)= 12-x/(2-x+6)

a= 12-x

exis [7]

Answer: 63 nurses and 14 doctors

so you know the ratio is 9:2. that means for every 9 nurses there are 2 doctors. i didn't make an equation but i counted it.

if theres 9 (9*1) nurses theres 2 (2*1) doctors

if theres 18 (9*2) nurses theres 4 (2*2) doctors

if theres 27 (9*3) nurses theres 6 (2*3) doctors

you get the point so i multiplied 7 to 9 and 7 to 2, which means:

if theres 63 (9*7) nurses theres 14 (2*7) doctors

i hope this helps :)

We have the following function and point:
 The originial function is f (x).
 The original function contains the point (-3, -3).
