Hello! 

I assume you want to know the number of students (n) who listed basketball as their favourite sport!

3*n - 13 = 347

Add 13 to both sides

3*n = 360

Divide both sides by 3

n = 120.

There are 120 students who listed basketball as their favourite sport.

Hello and welcome to web2! 

A linear equation is one in which the dependent variable (y, say) depends directly on the independent variable (x) raised to the power 1, but not on powers of the independent variable other than 1.

For example y = 2x + 3 is a linear equation, but y = 2x² + 3 isn't.  (Note that x is the same thing as x¹)

y = 5x - 9 is linear, but y = √x -9 isn't.

...

9x9=81 so 81 is your answer.

is it a joke if not 81

1,028 is the answer right or wrong

Hello Anonymous,

Well, Math is hard either because our brains don't understand it (causing the human attached to the brain to stress over math because it is "so hard") or because we just do not like it (I have read that if the human doesn't like something, the brain automatically tells the human that it is hard).

Hope that helps!
