What equation is equivalent to 3x+6=4x+7
1 answer:
Answer:
x=-1
Step-by-step explanation:
The first thing we can do is subtract 3x from both sides (it makes solving the equation easier if you get rid of the variable first).
3x+6=4x+7
<u>-3x -3x</u>
6=x+7
All we need to do now is subtract 7 on both sides.
6=x+7
<u>-7 -7</u>
-1=x or x=-1 (they both mean the same thing!)

You have to calculate how many ways you can select six things (r)
from a set of 9 things (n). (See attached formula).
9! / 6! * (3!) =
9*8*7 * 6! / 6! * 3! =
9*8*7 / 3! =
3 * 4 * 7 = 84 lineups
