15=x+13
EASY. subtract 13 from both sides, and it's (x=2)
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 BS. You had not had time to spend any time looking at it.
x+11=9
Post it and I will check it.
18
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
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.

15=x+13
do i do the 15 or 13
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?
is it 26
add
No.
Remember you want to get the x alone.
i dont get it
Study that website I linked.
I'm sorry.
Please talk with your teacher. You may need a personal tutor.
what about -12x=12
do i multiply
No. Divide both sides by -12
so that would be 1
-9x=27
am i multiplying 9
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.
-4=x-22
would it be add
thank you i didnt even know that
Let's see what you learned from the last problem.
What do you think you should do?
