Answer: Anthony drove 12 miles and Yareli drove 48 miles.
Explanation:
let a = the distance Anthony drove
let y = the amount of time yareli drove
a + y = 60
y = 4a
since 4a is equal to y, you can substitute it in for the y’s in the first equation
a + 4a = 60
5a = 60
5a/5 = 60/5
a = 12
so Anthony drove 12 miles
now let’s plug that result into the y=4a equation to find out how many miles Yareli drove
y = 4a
y = 4(12)
y = 48
now let’s check to see if it works
48 + 12 = 60
12 x 4 = 48
it works :)
so Anthony drove 12 miles and Yareli drove 48 miles.
