Lauren's age now is (m + 26)/2 years in terms of m.

• Let the Lauren's present age be x.

• Now 11 years ago, lauren was half as old as mike will be in 4 years.

• Mike's present age is given as m

According to the given condition ,

x - 11 = 1/2(m+4)

2x - 22 = m + 4

2x = m + 26

x = (m + 26)/2

• Lauren's present age will be (m + 26)/2 years.
