Answer:

Mother = 30\ years

Son = 10\ years

Step-by-step explanation:

Given

M = Mother

S = Son

From the first statement:

M = 3S

From the second:

M - S = 20

Required

Find M and S

We have:

M = 3S and

M - S = 20

Substitute M = 3S in M - S = 20

3S -S =20

2S = 20

Divide both sides by 2

S = 10

Substitute S = 10 in M = 3S

M = 3 * 10

M = 3 0

Hence;

Mother = 30\ years

Son = 10\ years
