Rachel took a two day road trip last weekend. She drove 65 miles less on Sunday than she did on Saturday. If twice the miles was driven on Sunday is 373 more than the number of miles driven on Saturday, how many moles did she drive each day?

Rachel drove on Saturday = 503 miles

Rachel drove on Sunday = 438 miles

Step-by-step explanation:

As given ,  Rachel drove 65 miles less on Sunday than she did on Saturday.

Let us suppose

Rachel drove on Saturday = x

Rachel drove on Sunday = y

then, we get

y = x - 65

Also given, If twice the miles was driven on Sunday is 373 more than the number of miles driven on Saturday

then , we get

2y = 373 + x

⇒2(x - 65) = 373 + x

⇒2x - 130 = 373 + x

⇒2x - x = 373 + 130

⇒x = 503

∴ we get

Rachel drove on Saturday = x = 503

Rachel drove on Sunday = y = x - 65 = 503 - 65 = 438

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
