Answer:
n = 11.1
Step-by-step explanation:
2.1n = 18 + 5.31
2.1n = 23.31
n = 23.31 / 2.1
n = 11.1
Hope that helps!!!!
2.1n-5.31=18
+5.31=+5.31
2.1n= 23.31
23.31/2.1 = 11.1
n=11.1
To check answer plug 11.1 in to the spot of n & multiply it by 2.1 then subtract from 5.31 and you should get 18 .
+5.31=+5.31
