Answer:
p = -7
Step-by-step explanation:
-6p+7+21p=14+16p
Collect Like Terms.
15p+7=14+16p
Move Terms
15p-16p=14-7
Collect Like Terms Subtract
-p = 7
- change the signs
-6p+7(1+3p) = 2(7+8p)
Now, let's expand this equation
-6p + (7*1) + (7*3p) = (2*7) + (2*8p)
-6p + 7 + 21p = 14 + 16p
Collect like terms
-6p + 21p - 16p = 14 - 7
-22p + 21p = 7
therefore,
