For z=2⇒ 2y+2=12
2y=12-2
2y=10
y=10:2
y=5
x - y+z=6
x - 5 + 2=6
x -3 =6
x=6+3
x=9
The answer is D,I might be wrong tho

Answer:
E. 22
Step-by-step explanation:
Hello!
We know that b>6, and we are asked to find the possible values for 3b + 3.
Let's directly substitute 6 for b:
Now, because b is greater than 6, and not equal to 6, any value greater than 21 will work.
The correct option is E. 22.
Hint: substitute 2^x by say 't': t = 2^x, then you'll have an inequality with a second order polynomial (2/t-4*t<7--> ...). In the end something like t^2 + a*t+b > 0, for some values of a and b, find the roots and get the intervals where it is satisfied.
