82.78(p+ 11.892)=72.8464 do not round your answer

1 answer

To solve for p, we can start by subtracting 11.892 from both sides of the equation:

82.78(p + 11.892) - 11.892 = 72.8464 - 11.892
82.78(p) + 82.78(11.892) - 11.892 = 60.9544

Now, simplify the equation:

82.78p + 997.09376 - 11.892 = 60.9544
82.78p + 985.20176 = 60.9544

Next, subtract 985.20176 from both sides of the equation:

82.78p = 60.9544 - 985.20176
82.78p = -924.24736

Finally, divide both sides of the equation by 82.78 to isolate p:

p = (-924.24736) / 82.78

So, the exact solution for p is:
p ≈ -11.155
