Answer 1

Answer:

5.-A, 7-D, 8-A

Step-by-step explanation:

7- Let's take father's age as '3$x$'

   Then the son's age will be '$x$'

   They've given us the age of the son, which is 15 years old.

    So father's age will be 3(15)

                                         =45 years

8) 2$x$-3=7

 = 7+3=2$x$

 =10=2$x$

 therefore, $x$=5

Answer 2
