Question

How would i do the following : 5+7(x+1)=12+10x

Answer 1

first distribute the 7, so it's 5+7x+7=12+10x
then simplify the left side to 12+7x=12+10x
subtract 7x from both sides: 12=12 +3x
Subtract 12 from both sides: 0=3x
so x=0

Answer 2

5+7(x+1)=12+10x
5+7x+7=12+10x
12+7x=12+10x
12=12+10x-7x
12=12-3x
0=3x
0=x

Answer 3

The answer is 0, What if i leave it as 3, would that be wrong?

Answer 4

oh yes, absolutely! it's zero, that's very different from 3!

Answer 5

How did you get O or 3 bye itself

Answer 6

0=3x, so then divide both sides by 3. you get 0=x

Answer 7

and if you want to check if 3 or 0 is the right answer, plug it into the equation, and see if you get the same number on both sides
