Answer:
N= 4
Step-by-step explanation:
3(3)+2n=17
9+2n=17
-9. -9
2n=8
2. 2
N=4
To answer this question, we have to follow the next steps:
1. Subtract 13 to both sides of the equation:

2. Divide the resulting equation by 5 to both sides of the equation:

Therefore, the value that solves this equation is W = 21/5 or W = 4.2 (using a decimal expression.)
3.7÷(1 2/9 −0.4) = 166.5/45 ÷ 37/45 = 4.5
0.4 = 40/100 = 2/5
2/5 = 18/45
1 2/9 = 11/9 = 55/45
55/45 - 18/45 = 37/45
3.7 = 370/100 = 18.5/5 = 166.5/45
