I tried working them out seperately, T-70= 20a and doing the same with the other particle, im mostly confused what to do with the multiple forces there are

220-60-T=resultant on right, which is equal to?
You get a simultaneous equation and u can solve for a. Then to find T, plug it into one side's F=ma
