Pleeeease help me translate the following sentence into an equation using n to represent the unknown number. Then solve the equa
anygoal [31]
Six more than: 6 + or + 6
twice a number: let n represent the unknown number: 2n

6 + 2n = 16

So, the answer is either c or d

So, solve the equation

Subtract 6 on both sides of the equation

2n=10

Divide by 2 on both sides of the equation

n=5

So, the answer is C
