Were you able to figure this one out? add 4 to both sides to get 2m/3 = m+4. Then multiply away the denominator but be careful - when you multiply on the right, the 3 must multiply to everything on the right, so it looks like 3(m+4). This will give you 2m=3m+12. Then move the 3m to the left for -1m = 12, which will give m=-12.]]> 2017-02-07 09:28:14 UTC https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/152067586 chloegassoub https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/152068438 1/2 (1-3x)=-1]]> 2017-02-07 09:32:01 UTC https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/152068438 pickleadnyt https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/152069926 It doesn't - it makes -7/3. Your first step is to move the 10 over to the other side. When combined with the 9, will make -1. Then multiply the denominator 7 to both sides so you are left with 3p = -7. Then divide away the 3.]]> 2017-02-07 09:39:17 UTC https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/152069926 avi27shrm https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/153865151 1/5(4-3x)=-1]]> 2017-02-14 20:35:43 UTC https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/153865151 dmjzaharko https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/154262424 2017-02-16 10:52:51 UTC https://padlet.com/dmjzaharko/gtg9ctxns9pd/wish/154262424
