The equation is s = 27 + l, and Lea ran 19 miles
The statement is given as:
Represent the miles they ran with the first letters of their names.
So, we have
s = 27 + l
s = 46
How many miles did Lea run?
Substitute s = 46 in s = 27 + l
46 = 27 + l
Subtract 27 from both sides
l = 19
Hence, the equation is s = 27 + l and Lea ran 19 miles
