x+11=9

You need to move the 11 to the other side. Since it's a positive number, you need to subtract it from both sides;

x = -2

x-17=-9
x=26
Answered by Ms. Sue
No.

Add 17 to both sides.

Remember, you're trying to get the number to the other side. So you add a negative number to both sides. You subtract a positive number from both sides.

do i do the 15 or 13
Answered by Ms. Sue
You need to move 13 so that the x is on one side and the numbers are on the other.

Are you going to add or subtract 13?

-9x=27
Answered by Anonymous
am i multiplying 9
Answered by Ms. Sue
It would be -1. A positive divided by a negative is a negative.

To find the numerical value of x, you need to divide 27 by -9.

You clearly did not study the web site that was given to you. You had posts about every 3 minutes for a half hour, at which time you said you didn't understand the web site. I call <b>BS</b>. You had not had time to spend any time looking at it.
