Answer is n = 3

Step by step

2 times means 2 multiplied
The sum means add
Of a number and 5 means n + 5
Is means equal =
16 is the answer to the equation

Put this into an equation

2 (n + 5 ) = 16

Distributive property

2n + 10 = 16

Subtract 10 from both sides to isolate variable

2n +10 -10 = 16 -10

Combine like terms

2n = 6

Divide both sides by 2 to solve for n

2/2 n = 6/2

n = 3
