it will be 3*2/3x=21.3 i think
anonymous
  • anonymous
how did you get 21.3?
anonymous
  • anonymous
i mean 21
anonymous
  • anonymous
no wait you multiply 3 in both sides
anonymous
  • anonymous
help me someone
anonymous
  • anonymous
right, you multiply by 3 on both sides, so what happens then?
anonymous
  • anonymous
then you multipy and x=63 right
anonymous
  • anonymous
for future reference when you mean 21 times 3 , write down 21*3, and not 21.3 :)
anonymous
  • anonymous
okay thank you
anonymous
  • anonymous
can u help me with -2(3x-6)=24
anonymous
  • anonymous
no, x is not 63, 2x = 63.
anonymous
  • anonymous
you multiplied by 3 on both sides, but the 2 is still there, remember?

There are 200 lockers in your school, numbered 1 through 200 consecutively. The lockers are all closed to begin. Student #1 walks down the corridor and opens all the lockers that are numbered with a multiple of 1, thereby all the lockers are opened. Student #2 then walks down the corridor and changes the status (closed lockers are opened; open lockers are closed) of all the lockers that are numbered with a multiple of 2 (note that in the case of Student #2, this only involved closing lockers). Student #3 then walks down the corridor and changed the status of all the lockers that are numbered with a multiple of 3. By the end of this scenario, 200 students will have walked down the corridor, in numerical order, with each student changing the status of those lockers that are numbered with a number that is a multiple of the student’s number. At that point, which of the lockers are open? More importantly, why are these lockers open?

  • anonymous
yes, you have to divide both sides by 2. so your answer is x = 63/2
