Answer:
Step-by-step explanation:
Let's do like-terms first which on the right side has the 2p:
17-2p=4p+5
Then make the variables on one side:
17=4p+2p+5
17=6p+5
Let's put that 5 on the other side:
17-5=6p
12=6p
Lastly, divide 6 to get a final remaining p.
12/6=p
2=p
Hope you understand :)
Step 1. Multiply first equation with -3 and the second one with 2. You'll get:

Step 2. Add both equations together. You'll get:

, which gives x = -2
Step 3. Replace x = -2 in the first equation and calculate y.

The solution is: x=-2, y=5
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}
