You can only add or subtract like terms. So, you subtract 9x from 2x, which gives you -7x. Then subtract -9 from 3 to get -6. And you are left with -7x -6.
Subtract the absolute value of the smaller number from the absolute value of the larger number. The answer will have the sign of the larger numbers.
The same way you would add or subtract whole numbers, leaving the denominators alone.
wich one
You add all the numbers with + signs and subtract all that have minus signs.
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
Yes. A negative subtracted by a negative is a positive. Just remember that two like signs become a positive sign, and two unlike signs become a negative sign.
Ignore the signs and subtract the smaller number from the larger one.
signs are different.... Find the difference.... KEEP THE LARGER SIGN signs are the same... COMBINE AND KEEP THE SIGN
In addition different signs you subtract and give the sign of the bigger number. Ex: 6+(-8)= -14
fist then the kick then the uppercut
Subtract the numerators as we normally subtract them and then divide the resultant by the denominator. It's just simple like that.
yes it will be. yes... if (-3)-5 is a possible problem, then the answer will be -8... it is like removing the negative signs, adding, then placing back the negative sign
You add or subtract only the numerators
You take the value of the first, and take it away from the second, and depending on the signs that are similar (positive/negative) they can cancel and override each other.
we can use the number line as a model to help us visualizeadding and subtracting of signed.
