Make an equation: J = 1/2F - 10 Where 'J' represents Justin's age and 'F' represents his Father's age. Plug in 12 for J: 12 = 1/2F - 10 Add 10 to both sides: 22 = 1/2F Divide 1/2 to both sides or multiply by its reciprocal, 2: F = 44

22 because 12 plus 10 is 22, or because 10-12=2  2+20=22  20+2 because 10nis half of 20
