5p - 14 = 8p + 4
take constants to the right and variable to the left
5p - 8p = 4 + 14
simplify
-3p = 18
multiply both sides by -1 and take 3 to the denominator of the right
p = -18 / 3
p = -6

First group common items:
Subtract 5p from both sides of the equation:
Then subtract 4 from both sides:
5p - 14 - 5p - 4 = 8p + 4 - 5p - 4
Then simplify:
5p - 5p - 14 - 4 = 8p - 5p + 4 - 4
-14 - 4 = 8p - 5p
-18 = 3p
Now divide both sides by 3:
-18 / 3 = 3p / 3
-6 = p
And you're done.

5p - 14 = 8p + 4
5p - 14 - 5p = 8p + 4 - 5p
-14 = 3p + 4
-14 - 4 - 3p + 4 - 4
- 18 = 3p
- 18/3 = 3p/3
- 6 = p
The answer is p = -6
The solution set is { - 6 }
Insert the p value into the equation
- - - - - - - - - - - - - - - - - - - - - - - - - -
Check
5p - 14 = 8p + 4
5(-6) - 14 = 8(- 6) + 4
- 30 - 14 = - 48 + 4
- 44 = - 44

bring 5p right side n take 4 to left
ul get -14-4=8p-5p
3p=-18
p = -18/3
p= - 6

W HEN YOU HAVE A VARIABLE TERM ON BOTH SIDES, ELIMINATE ONE, BY ADDING ITS OPPOSITE TO BOTH SIDES. I ALWAYS CHOOSE TO ELIMINATE THE ONE ON THE RIGHT.
5P-8P-14=8P-8P+4
-3P-14=4
ADD 14 TO BOTH SIDES
-3P=18
DIVIDE BOTH SIDES BY -3
P=-6

5p-14=8p+4
5p-8p=14+4
p(5-8)=18
p*(-3)=18
p=18/(-3)
p=6*3/-3
p=-6
