Step-by-step explanation:

Let present ages of marina be 'm' and daughter be 'd'

Four years ago means m-4 and d-4. According to the first statement

m-4 = 3*(d-4). Solving this

m -3d +8 = 0 --- (1)

Six years from now means

m +6 and d+6. According to second statement

m + 6 = 2*(d+6). Solving this

m -2d -6 = 0 ----(2)

Just solve eq. 1 and 2 to get the 'm' and 'd' which will be the present age.
