I don't do tother peoples homework so I'll show you how to solve 3x=6
you multiply both sides by the invers3 of the x coeficient (1/3)
1/3*3x=1/3*6
x=2

same thing if you have 1/3x=3

you multiply both sides by the inverse of the x coeficient (just flip the fraction)
so 3*1/3x=3*3
x=9
to find the inverse of a fraction just flip it, to find the inverse of a whole number put a one over it.

once you have absolute fee, you should discover the two the beneficial and the unfavourable values that could desire to be interior the brackets considering as quickly as you're taking unquestionably the fee the respond is often going to be beneficial no remember what's contained in the brackets, no remember if beneficial or unfavourable. Absolute fee is definitely a level of the gap a extensive kind is from 0 in the two path. it may desire to flow contained in the beneficial or unfavourable path, in spite of the undeniable fact that, distance is often beneficial so the respond ought to be beneficial. you could not return and forth a unfavourable distance no remember how hard you're able to be able to objective. So, in case you have a difficulty like #one million, you placed it up this way: |x-6| = sixteen you want to sparkling up for x, yet by means of fact it incredibly is interior of an absolute fee bracket, you should take that under consideration and set up your answer the two approaches, utilising +sixteen and -sixteen as solutions, even nonetheless you be attentive to that absolute fee is often beneficial contained in the top. yet, that's how we are in a position to be sure the two values of x which will provide us sixteen as an answer. Now take off unquestionably the fee brackets, and rewrite the difficulty as follows: x - 6 = sixteen OR x - 6 = -sixteen then sparkling up for x in each case. x - 6 + 6 = sixteen + 6 OR x - 6 + 6 = -sixteen + 6 x = 22 x = -10 So, x can equivalent 22 OR x can equivalent -10. X can not equivalent the two 22 and -10 on the comparable time, yet merely one after the other, the two one or the different. Plug on your solutions one after the other to work out in the event that they the two paintings or no longer. If certainly one of them does not paintings, do no longer use it, then merely use the single which works. #2 is complete the very comparable way, yet #3 is a splash distinctive. 3) |x| = 2x + 6 so, x = 2x + 6 OR x = - (2x + 6) x = -2x - 6 x - 2x = 6 x + 2x = -6 -x = 6 3x = -6 x = -6 OR x = -2 So, your answer right here could be x = -6 or x = -2, relies upon on which one you like at which era, yet nevertheless, it incredibly is the two. yet, you should ascertain your solutions to work out in the event that they paintings contained in the difficulty. i think of you will discover that a sort of solutions does not paintings. decide which one which's and discard that answer, use merely the single which makes the assertion genuine (suits into the difficulty and makes it pop out suitable). Make experience?

1/8c=18
or 1=18*8c
or 8c=1/18
or c=1/(18*8)
