Answer:
1.60 L of 10% solution
0.40 L of 35% solution
Step-by-step explanation:
If x = amount of 10% saline solution, and y = amount of 35% saline solution, then:
x + y = 2
0.10x + 0.35y = 0.15(2)
Solve with substitution:
0.10x + 0.35(2 − x) = 0.15(2)
0.10x + 0.70 − 0.35x = 0.30
0.40 = 0.25x
x = 1.60
y = 0.40

Answer:
x = 89
Step-by-step explanation:
106 - 17 = 89
7 times -6x, because “a number” can be replaced with x
