WebI having difficulty with word problem of system linear equation in three variables. Q: The perimeter of a triangle is 36 inches. Twice the length of the longest side minus the length of the shortest is 26 inches. the sum of the length of the longest side and twice the sum of both the other side length os 56 inches. find the side length. WebTreat the missing variable as having a coefficient of 0. Otherwise you solve them the same way. Here is how I would solve that problem. This involves a variation on substitution that will not likely be taught in your class, but I find much easier to work with.
