What is the answer to Y=19-2x. X=3
The empirical formula for the compound X3Y12 is X1Y4. This is determined by dividing the subscripts by the greatest common factor, which in this case is 3 for X and 12 for Y.
Name the two numbers x & y , you can form these equations:x + y = 21x - y = 19Solve the system by substitution:x - y = 19 --> x = 19 + y19 + y + y = 2119 + 2y = 212y = 2y = 1But, X + y = 21X + 1 = 21x = 20
LCM is found by factoring, but then you must use all from each, with no repeatsFind LCM for 14x2y3z and 21 xy4factor 14x2y3 = 2.7 x x y y y zfactor 21 xy4 = 3.7 x y y y yfactors 2, 7, x , x , y, y, y, z, 3, y now multiply all theseso LCM = 2.7 x x y y y z . 3 y = 42x2y4zthis can give us a few rulesuse all numerical factorsuse all variable factors with the Largest exponent from each.

GCF is found by looking for common factors, real numbers or variables.Find GCF for 14x2y3z and 21 xy4factor 14x2y3z = 2.7 x x y y y zfactor 21 xy4 = 3.7 x y y y ycommon factors 7, x, y, y, y 3 y's in each but only 1 x , don't use z it is not in both terms ( it is not a common factor)multiply to get GCF 7xy3LCM is similar in that you start by factoring, but then you must use all from each, with no repeatsFind LCM for 14x2y3z and 21 xy4factor 14x2y3 = 2.7 x x y y y zfactor 21 xy4 = 3.7 x y y y yfactors 2, 7, x , x , y, y, y, z, 3, y now multiply all theseso LCM = 2.7 x x y y y z . 3 y = 42x2y4zthis can give us a few rulesthe LCM is greater than (or equal to) the original termsbut the GCF is ledss than.Sounds backwards, but a factor is only one part, and even the greatest part is less than the whole.Also For LCM we use each variable with the LARGEST exponent.for the GCF we use only common variables, and use the SMALLEST exponent.All factors are NOT necessarily in the GCF ( notice 2, 3, and z above)But all factors are in the LCM
