Answer:
8 pounds of 4% solution of borax
Step-by-step explanation:
Let x be the 4% solution
24 pounds of 12% solution
obtain a 10% solution of borax that is (x+24) pounds
4% is 0.04 and 12% is 0.12 , 10% is 0.1
solve the equation for x
so 8 pounds of 4% solution of borax
Step 1. Divide by the numbers 0.25 (1 divided by 4):
0.25 x +2=5 divided by 8x-5
Step 2. Divide the by the numbers 0.625 (5 divided by 8):
0.25 x +2=0.625x-5
Answer: 0.25 + 2= 2.25
