Answer:

<u><em>Steven is 15 and one half years old now</em></u>

Step-by-step explanation:

<u />

Linear equations

Sometimes we need to know the value of a variable in a given equation and that variable is given as a polynomial of degree 1. Solving for that variable means isolating it and replacing the other known values

Steven was 7 years old eight and one-half years ago. If we call x as the actual age of Steven, his age eight and one-half years ago was

x-8\frac{1}{2}

We know he was 7 years old then, so

x-8\frac{1}{2}=7

We need to know his actual age, so let's solve for x, adding 8\frac{1}{2} to each side of the equation

x-8\frac{1}{2}+8\frac{1}{2}=7+8\frac{1}{2}

Simplifying

x=15\frac{1}{2}

Steven is 15 and one half years old now
