Question

When 40 is added to the number of miles Karen ran last week, the result is the same as adding 10 to 4 times the number of miles she ran last week.

How many miles did Karen run last week?

___ miles

Answer 1

"40 is added to the number of miles Karen ran last week" can be written as x + 40

"adding 10 to 4 times the number of miles she ran last week" can be written as 4x + 10

so x + 40 = 4x + 10. solve for x
