put this solution on YOUR website!50+x=89
First, subtract 50 from each side. (equals subtracted from equals the differences are equal). This will isolate x by itself and that's what we want to do. When we isolate x by itself, we will then know what the value of x is.
50-50+x=89-50
On the left side, we know that 50-50=0 so now we only have x remaining on the left side.
0+x=39 When we subtract 50 from 89 on the right side, we have 39 left
So our answer is x=39

substitute x=39 into the original equation and we have:
50+39=89
89=89
