Answer:
x = age of coin 1
7 + 2*x = age of coin 2.
Step-by-step explanation:
We have two coins, let's denote the ages as:
x = age of coin 1
y = age of coin 2.
Then, the statement is:
"one coin is seven more than twice as old as another."
let's suppose that this refers to y, then:
y = 7 + 2*x
So now we can represent the ages of both coins with only one variable, x.
x = age of coin 1
7 + 2*x = age of coin 2.
