Answer:
n = 6
Step-by-step explanation:
n - 10= 5/6n - 7 - 1/3n
n - 10 = 15/18n - 7 - 6/18n
n - 10 = 9/18n - 7
18/18n - 10 = 9/18n - 7
9/18n = 3
1/2n = 3
n = 6
Let be M the set of the real numbers less thant 69
so we write it as follow M = { x∈R / x ∠ 69}
X in litres is 67% herbicide
y in litres is 46% herbicide
{x+y=42
{0.67x+0.46y=42*0.55
{67x+46y=2310
{46x+46y=1932
21x=378
x=18 litres
