Verified Answer :

n would equal 3 I'm sure

Simplifying
2.9n + 1.7 = 3.5 + 2.3n

Reorder the terms:
1.7 + 2.9n = 3.5 + 2.3n

Solving
1.7 + 2.9n = 3.5 + 2.3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-2.3n' to each side of the equation.
1.7 + 2.9n + -2.3n = 3.5 + 2.3n + -2.3n

Combine like terms: 2.9n + -2.3n = 0.6n
1.7 + 0.6n = 3.5 + 2.3n + -2.3n

Combine like terms: 2.3n + -2.3n = 0.0
1.7 + 0.6n = 3.5 + 0.0
1.7 + 0.6n = 3.5

Add '-1.7' to each side of the equation.
1.7 + -1.7 + 0.6n = 3.5 + -1.7

Combine like terms: 1.7 + -1.7 = 0.0
0.0 + 0.6n = 3.5 + -1.7
0.6n = 3.5 + -1.7

Combine like terms: 3.5 + -1.7 = 1.8
0.6n = 1.8

Divide each side by '0.6'.
n = 3

Simplifying N = 3
