But, I am trying to solve the same type of problem with the answer known and one of the numbers an unkown, such as: 34 x X/34 + X = 21.1555 Everything I have tried tells me I don't know how to approach this problem Can you please help? Thanks, Quaedan Answer by Edwin McCravy(13211)   (Show Source): You can put this solution on YOUR website! ```34 x X/34 + X = 21.1555 Are you sure that it shouldn't have been 34 + 56/34 + 56 = x instead? I say that because in 34 x 56/34 + 56 = x the 34's will just cancel out and you'll always get one-half what the second number is. If it was supposed to be 34 + X/34 + X =x 34 + X/34 + X = 21.1555 You multiply through by 34 getting Edwin```
