Answer:

n=6

Step-by-step explanation:

5n-17=2n+1

Subtract 2n from each side

5n-2n-17=2n-2n+1

3n -17 = 1

Add 17 to each side

3n -17+17 = 1+17

3n = 18

Divide by 3

3n /3 = 18/3

n=6

$\large \sf \star \: \green{Answer }\: \star$

$\small \sf \fbox{n = 6}$

<h3>Step-by-step explanation:</h3>

$\small \sf \mapsto \: 5n \: - 17 = 2n + 1$

subtract 2n from both side

$\small \sf \mapsto \: 5n \: - 2n \: - 17 = 2n \: - 2n + 1$

$\small \sf \: \mapsto \: 3n \: - 17 = 1$

Add 17 to both side

$\small \sf \mapsto \: 3n \: - 17 + 17 = 1 + 17$

$\small \sf \mapsto \: 3n \: = 18$

Divide 18 by 3

$\small \sf \: n \: = \frac{18}{3} \\$

n = 6
