Use the information to write an equation with variables
on both sides. let x represent kim's age.
bob is 4 years older than twice kim's age.
paul is 1 year younger than 3 times kim's age.
bob and paul are the same age.
which equation can be used to determine kim's age, x,
from the information about bob and paul?
4x + 2 = 3x + 1
4x + 2 = 3x + (-1)
2x + 4 = 3x + 1
2x + 4 = 3x + (-1)
