what is 13x-8= -5x+10

Nnesha (nnesha):

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

OpenStudy (sleepyjess):

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?

OpenStudy (cookielate):

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 (cookielate):

hello

OpenStudy (sleepyjess):

oh, sorry, didn't get a notification

OpenStudy (sleepyjess):

yep, so 18x = 18, what is the opposite of multiplying?

OpenStudy (cookielate):

division

OpenStudy (cookielate):

@sleepyjess

OpenStudy (sleepyjess):

yep, so 18/18 = ?

OpenStudy (cookielate):

1

OpenStudy (sleepyjess):

Yep, therefore, x = 1

OpenStudy (cookielate):

thanks

OpenStudy (cookielate):

so much
