\(\bf {\color{brown}{ \cancel{3}}}\cdot \cfrac{2x-20}{\cancel{3}} ={\color{brown}{ 3}}\cdot 2x\)

so would i have 6x-60=6x ?
UsukiDoll
  • UsukiDoll
by multiplying 3 on both sides... the 3 for the left side ends up being canceled out
anonymous
  • anonymous
so .... 2x-20= 3 times 2x ? im lost .. im not good at math
UsukiDoll
  • UsukiDoll
or another way of seeing that there is cancellation \[\large \frac{(3)(2x-20)}{3} =2x (3)\] \[\large \frac{(6x-60)}{3} =2x (3)\] \[\large 2x-20=6x\]
UsukiDoll
  • UsukiDoll
yeah you will have 2x-20= 3(2x) which becomes 2x-20=6x
anonymous
  • anonymous
okay i understand that part now
UsukiDoll
  • UsukiDoll
now we just have to have all variables to the left and all numbers to the right so add 20 to both sides and subtract 6x to both sides

can i solve it like a regular equation ....|dw:1438127165206:dw|

UsukiDoll
  • UsukiDoll
it's ok. I just want to check... just to be sure
UsukiDoll

|dw:1438127376054:dw| it's correct!
anonymous
  • anonymous
i think thats right its in the answer box which is −5 −3 2 13
UsukiDoll
  • UsukiDoll
the answer should be the same even if the terms are rearranged (variables to the left, numbers to the right) |dw:1438127444700:dw|
