Answer:
Here
Step-by-step explanation:
We move all terms to the left:
7+9x-(6x-2)=0
We get rid of parentheses
9x-6x+2+7=0
We add all the numbers together, and all the variables
3x+9=0
We move all terms containing x to the left, all other terms to the right
3x=-9
x=-9/3
x=-3
If you use your subtraction right when you use deceleration as for example like 4.5 from 79 well you know it had to slow down so the correct Answer for this would end up as 17 .5 Try the easy way like
79 dived by 4.5 would get you the same answer but don't divide backwards you will get an in correct answer
hope i helped;)
