show me what you did with this 9(4x4)=3(12x+7)
 one year ago

godorovgBest ResponseYou've already chosen the best response.1
work with just the nine ony

godorovgBest ResponseYou've already chosen the best response.1
do this only 9(4x4) I want to see your steps.

tootie149Best ResponseYou've already chosen the best response.0
9(4x4)=3(12x+7) 36x4=36x+7 36x4+4=36x+7+4 36x36x=11 ok here is where I get lost because there is no x so is the answer real or empty
 one year ago

godorovgBest ResponseYou've already chosen the best response.1
yes so what is x now?
 one year ago

godorovgBest ResponseYou've already chosen the best response.1
no .. try again hint we want X alone.
 one year ago

tootie149Best ResponseYou've already chosen the best response.0
there is no x because 36x36x is nothing
 one year ago

tootie149Best ResponseYou've already chosen the best response.0
9*4=36 and 3*12 is 36
 one year ago

godorovgBest ResponseYou've already chosen the best response.1
okay first off there are not two 36x36x wrong. 9(4x4) doesn't = 36x36x no

tootie149Best ResponseYou've already chosen the best response.0
LOL I feel so stupid
 one year ago

godorovgBest ResponseYou've already chosen the best response.1
don't feel that way, sometimes i make little mistakes as well. we all learn in different ways.

now for the other side i got 36x+21

godorovgBest ResponseYou've already chosen the best response.1
hey one thing is slow down and do the steps, don't skip ahead just some friendly advice

campbell_stBest ResponseYou've already chosen the best response.0
tootie you are correct with your solution the expansion is 36x  36 = 36x + 21 subtract 36x from both sides and you get 36 = 21 no solution
 one year ago

godorovgBest ResponseYou've already chosen the best response.1
yes that is 36x+21 now again how do we get x alone?
 one year ago

campbell_stBest ResponseYou've already chosen the best response.0
its basically saying y = 36x  36 and y = 36x + 21 the lines are parallel ... so no intersection....
 one year ago

godorovgBest ResponseYou've already chosen the best response.1
campbell yes are right about 36x36x I wasn't at that point yet..

campbell_stBest ResponseYou've already chosen the best response.0
well tootie has actually has a correct piece of maths above... sorry...
 one year ago

tootie149Best ResponseYou've already chosen the best response.0
so the solution set is empty. right?

I was walking through the steps campbell

campbell_stBest ResponseYou've already chosen the best response.0
correct... just practise expanding terms in brackets...
 one year ago

campbell_stBest ResponseYou've already chosen the best response.0
the expansion of the pronumeral was correct... its just the constant term you need to be aware of

thank you for taking me through the steps I was not sure if I worked it right Godorovg

oh no trouble at all..

in this case if there is no x, then the set is empty, if it's all real number, all real number would work with the equation.

godorovgBest ResponseYou've already chosen the best response.1
right back at you I am a fan of yours now too. :)
