What is the solution to the equation −p−13=−43p+23(5p−6)?

Sagot :

Answer:

p = 125/73

Step-by-step explanation:

−p − 13 = −43p + 23 (5p − 6)

−p − 13 = −43p + 115p − 138

−p − 13 = 72p − 138

+p            +p

-----------------------------

-13 = 73p - 138

+138         +138

-----------------------------

125 = 73p

/73     /73

-----------------------------

125/73 = p

If you need the answer in mixed fraction, then it's --> p = 1 52/73

The solution to the given equation is p = - 1.71

To determine the solution of the given equation,

We will find the value of the variable, p, that satisfies the equation.

From the question, the given equation is

[tex]-p-13 = -43p+23(5p-6)[/tex]

To solve this,

First, Clear the brackets

[tex]-p-13 = -43p + 115p - 138[/tex]

Now, Collect like terms

[tex]-p +43p -115p = -138 + 13[/tex]

[tex]73p = -125[/tex]

Now, divide both sides of the equation by 73

[tex]\frac{73p}{73} = \frac{-125}{73}[/tex]

∴ p = - 1.71

Hence, the solution to the given equation is p = - 1.71
