5x+12 5/7=72 5/7
subtract 12 5/7 from each side
5x +12 5/7 - 12 5/7=72 5/7- 12 5/7
5x = 60
divide by 5 on each side
x = 60/5
x=12
Answer: -3
Step-by-step explanation: y=mx+b
m=slope
-(x-3)=-x+3
First, distribute -1 to x and -3.
-x+3=-x+3
As you can see, both sides are equal. You can continue to simplify:
Add x to both sides to get rid of the variable.
3=3 or infinitely many solutions because x can equal any number and still be equal to the other side.
