Question

Solve the proportion:
5
6
=
2
n
+
9
9

Answer 1

n= -43 over 2 or -43/2

Answer 2

n = -21.1/2

Explanation:

`56 = 2n + 99`

Collect like terms and simplify

`56 - 99 = 2n \\ - 43 = 2n`

Divide both sides of the equation by 2

`( - 43)/(2) = (2n)/(2)`

Simplify

`n = - (43)/(2) = - 21 (1)/(2)`
