Answer: P=51

--

Steps for Solving Linear Equation: 20−9=5p+12

--

Subtract 9 from 20 to get 11.


11=5p+12

Swap sides so that all variable terms are on the left hand side.


5p+12=11

Subtract 12 from both sides.


5p=11-12

Subtract 12 from 11 to get −1.


5p=1

Divide both sides by 5.


p=5-1

Fraction 5−1​≈−0.2 can be rewritten as −51​=−0.2 by extracting the negative sign.


p=-51
