Answer:
x=10,y=5,z=2
Step-by-step explanation:
x+15=2x+5
x=10
4y=8y-20
4y=20
y=5
10z-5=3z+9
7z=14
z=2
The natural number , n is 30
<h3>How to determine the value</h3>
Given;
GCF(n, 70) = 10
LCM(n, 70) = 210
We have that;
LCM(A,B) x GCF(A, B)= A x B
Then,
(n, 70) = n × 70 = 70n
10 × 210 = 2100
Equate the two expressions
70n = 2100
n =
n =
Thus, the natural number , n is 30
