Studdy Solution

STEP 1

Assumptions
1. We are given the equation 12p0.7=5p+3.212p - 0.7 = 5p + 3.2.
2. We need to solve for the variable pp.

STEP 2

First, we will collect all terms containing the variable pp on one side of the equation and the constant terms on the other side. To do this, we will subtract 5p5p from both sides of the equation.
12p0.75p=5p+3.25p12p - 0.7 - 5p = 5p + 3.2 - 5p

STEP 3

Perform the subtraction on both sides to simplify the equation.
12p5p0.7=3.212p - 5p - 0.7 = 3.2

STEP 4

Combine like terms on the left side of the equation.
7p0.7=3.27p - 0.7 = 3.2

STEP 5

Next, we will isolate the term with the variable pp by adding 0.70.7 to both sides of the equation to move the constant term to the right side.
7p0.7+0.7=3.2+0.77p - 0.7 + 0.7 = 3.2 + 0.7

STEP 6

Perform the addition on both sides to simplify the equation.
7p=3.97p = 3.9

STEP 7

Now, to solve for pp, we will divide both sides of the equation by 77.
7p7=3.97\frac{7p}{7} = \frac{3.9}{7}

STEP 8

Perform the division to find the value of pp.
p=3.97p = \frac{3.9}{7}

STEP 9

Calculate the value of pp.
p=0.5571428571...p = 0.5571428571...

STEP 10

If necessary, round the value of pp to a desired number of decimal places. For simplicity, we can round to two decimal places.
p0.56p \approx 0.56
The solution to the equation 12p0.7=5p+3.212p - 0.7 = 5p + 3.2 is approximately p0.56p \approx 0.56.
