6(2x-11)+15=21
12x-66+15=21
12x=21-15+66
12x=72
x=72/12
=6
This is the answer and way of solving
Hope this helps
All the best

Answer:
x + 31
Step-by-step explanation:
P = x + 2/(21 - 2x) + x + 2/(21 - 2x) + x + 2/(21 - 2x) + x
= x + 21/2 - x + x + 21/2 - x + x + 21/2 - x + x
= x + 21/2 + 21/2 + 21/2
=x + 31
