The equation is: $3 N + 1 = 7$

The solution is: $2$

#### Explanation:

You say: "one more than three times a number is 7".

So we start with a number $N$.

Then we multiply it by $3$ to get: $3 N$

Then we increase it by $1$ to get: $3 N + 1$

And we equal all of that to $7$: $3 N + 1 = 7 \to$ [ANS}

Solving: $3 N + 1 = 7$

$3 N + 1 - 1 = 7 - 1$

$3 N = 6$

$N = \frac{6}{3}$

N=2

"one more than three times a number is 7".

"one more than three times N is 7".

"one more than three times $2$ is 7".
