in order to solve for x first you should have all x values at one side and number without variables at other side
so first step to move -5x left side
OpenStudy (sleepyjess):
Are you trying to solve for x?
OpenStudy (cookielate):
yes need help !!!
OpenStudy (sleepyjess):
How do you think you get -5x off of the right side?
OpenStudy (cookielate):
subtract

It is already subtracting, so what is that opposite of subtraction?
OpenStudy (cookielate):
add
OpenStudy (sleepyjess):
Yep, so -5x + 5x cancels on the right side, now on the left we have 13x + 5x - 8. What is 13x + 5x?
OpenStudy (cookielate):
18
OpenStudy (sleepyjess):
18x, so now we have 18x - 8 = 10. What do we do to cancel -8?

divide
OpenStudy (sleepyjess):
nope, we are subtracting, so we need to add again
OpenStudy (cookielate):
so -8 add -8
OpenStudy (sleepyjess):
-8 + 8
OpenStudy (cookielate):
0

OpenStudy (sleepyjess):
yep, so 18x = 18, what is the opposite of multiplying?
OpenStudy (cookielate):

yep, so 18/18 = ?
OpenStudy (cookielate):
1
OpenStudy (sleepyjess):
Yep, therefore, x = 1
OpenStudy (cookielate):
