Question

Prove, in complete sentences, whether the left expression is equal to the right expression and discuss which property applies.

2(x − 3) 2x − 6 i already know that 2(x-3) =2x-6 =6/2 = x=3

Answer 1

nevermind i figured it out my self

Answer 2

Did you figure it out for sure. How did you get x=3, when there was no equation.....juest an expression. (No equal sign).!

Answer 3

You introduced the equal sign. Originally it was a "distribution" problem to show that the expression is an identy, There are infinite number of solutions

Answer 4

x could be 4, 2, -1 etc.

Answer 5

idk but i figured it out i just needed to figure out why the expression was the same , but i still dont know what property is used there

Answer 6

The distributive property. You distribute the 2 in the first expression getting 2x-6 which is identical to the right expression. And as you can see there are an infinite number of solutions including your result of 3.

Answer 7

i understand that i just said that x = 3 because when i did 2(x-3) it turned in to
2x-6 and then i did 6/2 which is 3 but i ddnt have to do that

Answer 8

When you substitute 3 for x in 2(x-3) you get 0.

Answer 9

i know that , i substituted it when i got 2x-6

Answer 10

Still 0
2(3)-6=0
0=0
If you had said x=5 then
2(5-3)=2(5)-6
10-6 = 10-6
4=4
You see it is an identity not a solvable equation.

Answer 11

i know i realized that after i did that because it didnt make sence , and thanks for the help

Answer 12

You are welcome, you will run into these type of problems and they can be confusing because there are no wrong answers lol.

Answer 13

yeah i know

Answer 14

i hate math

Answer 15

Well that makes it even more difficult, but try to do as much "practice" exercises that you can stand.

Answer 16

ok i will do , and its not that im bad at it its just too confusing
