Multiply 3.3 by everything in the parenthesis.
3.3x - 26.4 - x = 1.2
Combine like terms.
2.3x - 26.4 = 1.2
Add 26.4 to both sides.
2.3x = 27.6
Divide 2.3 on both sides.
x = 12
Hope this helps!

Answer:
<h3> 26²/₃ liters of 15% acid and 13¹/₃ liters of 33% acid</h3>
Step-by-step explanation:
Concentration Amount of Amount
of Solution Solution (L) of Acid
15% x 0.15x
33% y 0.33y
21% 40 0.21•40
x + y = 40 ⇒ x = 40 - y
0.15x + 0.33y = 0.21•40
0.15(40 - y) + 0.33y = 0.21•40
6 - 0.15y + 0.33y = 8.4
0.18y = 2.4
y = 13¹/₃
x = 40 - 13¹/₃ = 26²/₃
Answer:
