Use the distributive property to find the value of x.
noname [10]

Answer:

The value of x = 1.5

Step-by-step explanation:

Given:

-1.2(3 – x) = -1.8

To Find:

x = ?

Solution:

Distributive property:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

For example A(B + C) = A×B + A×C

Here we have,

-1.2(3 – x) = -1.8

Applying Distributive property we get ,

-1.2×3 -1.2×-x = -1.8

∴ -3.6 +1.2x = -1.8

∴ 1.2x =3.6-1.8\\\\1.2x=1.8\\\\x=\frac{1.8}{1.2} \\\textrm{multiply numerator and denominator by 10}\\x=\frac{1.8\times 10}{1.2\times 10}\\ \\x=\frac{18}{12} \\\\\\x= 1.5

∴ x = 1.5
