let the amount of 10% solution be x ml
then the amount of 15% solution must be 100-x ml
.10x + .15(100-x) = .12(100)
10x + 15(100-x) = 12(100)
10x + 1500 - 15x = 1200
-5x = -300
x = 60
then the amount of 15% solution must be 100-x ml
.10x + .15(100-x) = .12(100)
10x + 15(100-x) = 12(100)
10x + 1500 - 15x = 1200
-5x = -300
x = 60
