Question

What is the value of n in the equation below? 3n+ 16 = 7n Enter your answer as a whole number.

Answer 1

We have the next equation

$3n+16=7n$

First, we will subtract 7n on both sides

$3n-7n+16=7n-7n$$-4n+16=0$

then we subtract 16 on both sides

$-4n+16-16=-16$$-4n=-16$

Then we divide on both sides -4

$\frac{-4}{-4}n=\frac{-16}{-4}$

$n=4$

ANSWER

n=4
