Remember, if you add negative four, you're really subtracting four, or if you take away negative four, you're really adding four.
-n+(-4)-(-4n)+6
-n-4+4n+6 simplify
{-n+4n are like terms, so combine them. -n+4n is exactly the same as 4n-n, so flip them around if it helps. Just remember to keep the sign with the right number. Same thing with -4+6.}
Answer:
3n+2
Twenty five subtracted by six tenths times "x"
Answer:
x = 1/3
Step-by-step explanation:
3/5 + x = 14/15
we need to get a common denominator 15
3/5 * 3/3 = 9/15
9/15 + x = 14/15
subtract 9/15 from each side
9/15 - 9/15 + x = 14/15 - 9/15
x = 5/15
this simplifies divide the top and bottom by 5
x = 1/3
