Answer:

Step-by-step explanation:

Roberts's father=4x

Robert=x

After 5 years, the ages will be

4x+5 and x+5 because we just simply add 5 years to their ages

It says that the father will be 3x older. So,

3(x+5)=4x+5.   --this is the equation

3x+15=4x+5

    -5         -5

3x+10=4x

-3x     -3x

x=10
