put this solution on YOUR website!"Two times a first number decreased by a second number is 4" ___ 2f - s = 4
"The first number increased by twice the second number is 37" ___ f + 2s = 37
multiplying 1st eqn by 2 ___ 4f - 2s = 8
adding 2nd eqn (eliminating s)___ 5f = 45 ___ f = 9
substituting to find s ___ 2(9) - s = 4 ___ 14 = s
