You can put this solution on YOUR website!
2/5x+4/5x=36 or 6/5x=36 6=180x or x=1/30 proof 2/(5x1/30)+4/(5x1/30)=36
or 2/(5/30)+4/(5/30)=36 or 2/(1/6)+4/(1/6)=36 or 2x6+4x6=36 or 12+24=36 or 36=36
3a/4+2=17 or 3a/4=15 or 3a=60 or a=20
proof (3x20)/4+2=17 or 60/4+2=17 or 15+2=17 or 17=17
1+x/3+2-x/3 3+/-0=? you must have missed something on this one!!!!!!!!!!!!!
