Question

what will be the answer n(2n-1)=45​

Answer 1

Answer:

Simplifying

5(2n + -1) = 45

Reorder the terms:

5(-1 + 2n) = 45

(-1 * 5 + 2n * 5) = 45

(-5 + 10n) = 45

Solving

-5 + 10n = 45

Solving for variable 'n'.

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

Add '5' to each side of the equation.

-5 + 5 + 10n = 45 + 5

Combine like terms: -5 + 5 = 0

0 + 10n = 45 + 5

10n = 45 + 5

Combine like terms: 45 + 5 = 50

10n = 50

Divide each side by '10'.

n = 5

Simplifying

n = 5
