Hey there!
Okay let's get cracking :D
The equation is....  (2x/3) - 6 = 9
2x/3 = 15
2x = 45
<u>x = 22.5</u><u />    <----- And that is your answer!
I hope it helped!

Answer:
-22
Step-by-step explanation:
Which part of the function is valid when x = -6
The first part
h(-6) = 4x+2 and let x = -6
         =4(-6) +2
         = -24 +2
          =-22

Step-by-step explanation:
im terrible at explaining so-
 
        
             
        
        
        
X + y = 85
2x + 4y = 218
x = 85 - y 
<span>2(85 - y) + 4y = 218 </span>
<span>170 - 2y + 4y = 218 </span>
<span>170 + 2y = 218 </span>
<span>2y = 48 </span>
<span>y = 24 </span>
<span>x = 61</span>
