It would be easier to translate this into mathematical terms first. Let n = the unknown number
6n <span>> n + 20
Subtracting both sides by n to simplify: 6n - n </span><span>> n + 20 - n </span>5n <span>> 20 </span><span> Dividing both sides by 5: 5n/5 </span><span>> 20/5 </span>n <span>> 4 </span><span> Among the choices, the correct one is the second choice.
Simplify the equation as closely as possible to the form of y = mx + b. Check to see if your equation has exponents. If it has exponents, it is nonlinear (exponential). If your equation has no exponents, it is linear.
