15 + 24=39
All you are doing is adding 15 and 24 together making 39.
<span>Quantity Equation: t + s = 20 gallons
Lemon content Eq: 20t+70s = 40*20 gallons
</span><span>Modify for elimination:
2t + 2s = 2*20
2t + 7s = 4*20
</span><span>Subtract and solve for "s":
5s = 2*20
s = 8 gallons (amt. of 70% mix needed)
t = 20-8 = 12 gallons (amt of 20% mix needed)</span>
