Yra solves the equation as shown. - 3(x+2) = 9 1. - 3x - 6 = 9 2. - 3x = 15 3. x = - 5 the property tyra used in line 1 was the:

In line 1 distributive property is used

Step-by-step explanation:

Given equation :

-3(x+2)=9

Tyra solves it as :

1. -3x-6=9

2. -3x=15

3. x=-5

In 1. Distributive property is used i.e.

2. Addition property is used

i.e.If a=b then a+c=b+c

3. Division property is used

i.e. If a=b then

=

Therefore the property used in line 1 is :

Distributive property

no, because the sides are not congruent

this is not the answer this is just a question. is this middle school math?
