When Jayson is 10 his dad is four times his age and his mom is 2 years younger than his dad.  How old was Jayson's mom when he was born?
When Jayson is 10 his dad is 10 x 4 = <<10*4=40>>40 years old.
His mom is 40 - 2 = <<40-2=38>>38 years old.
When Jayson is born, his mom is 38 - 10 = <<38-10=28>>28 years old.
