What does the term 'linear equation' mean?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What is the value of n in the expression 6.25n + 3.50 = 34.75?

Back

To find n, subtract 3.50 from both sides and then divide by 6.25: n = (34.75 - 3.50) / 6.25 = 5.
