2 numbers equal 12 when added these same 2 numbers equal 9 when multiplied?
x+y=12 x*y=9 so y=9/x and substituting we have x+9/x = 12, multiply by x and we have: x2 + 9 = 12x or in standard form: x2 - 12x + 9=0 which solving using the quadratic equation gives: (+12 - sqrt(144-36))/2 and (12 + sqrt(144-36))/2 which gives x= 11.196, y = 0.804 and x= 0.804 and y = 11.196 You can search wikipedia for the quadratic equation.

If 8 a's 7 b's and 3 c's equal the same as 3 b's 6 a's and 6 c's and a dozen b's equal 3 and a equals two thirds of c what is c's value?
Given that 8a + 7b + 3c = 3b + 6a + 6c, and a = 2/3c, and if 12b = 3, then b = 1/4 Substituting for a and b, 16/3c + 7/4 + 3c = 3/4 + 12/3c + 6c Making 12 the common denominator, 64/12c + 21/12 + 36/12c = 9/12 + 48/12c + 72/12c Combining like terms, 100/12c + 21/12 = 9/12 + 120/12c Grouping like terms, 12/12 = 20/12c Simplifying fractions, 1 = 5/3c Multiplying both terms by 5/3, c = 3/5 And a = 2/3c = 2/3 x 3/5 = 2/5 Checking the answer using a = 2/5, b =1/4, and c = 3/5, Left side = 8a + 7b + 3c = 16/5 + 7/4 + 9/5 = 25/5 + 7/4 = 5 + 1 3/4 = 6 3/4 Right side = 3b + 6a + 6c = 3/4 + 12/5 + 18/5 = 3/4 + 30/5 = 3/4 + 6 = 6 3/4
