Which method correctly solves the equation using the distributive property? Negative 0. 2 (x minus 4) = negative 1. 7 Negative 0

xenn [34]

The method which is used to solve the provided equation using the distributive property is,

$\rm x = 4 + 8.5 = 12.5$

<h3>What is distributive property?</h3>

The distributive property is to make something easier to do or understand and to make something less complicated.

The given expression is $\rm - 0.2(x-4) = -1.7$ .

The expression can be written as

$\rm 0.2(x-4) = 1.7$

Divide both sides by 0.2

$\rm x-4 = \dfrac{1.7}{0.2} = 8.5$

Add 4 both sides, we have

$\rm x = 4 + 8.5 = 12.5$

Thus, the value of x is 12.5.
