Step-by-step explanation:

The question in English is

The age of 4 members of a family adds up to 70. Mom is 6 times bigger than her son and 10 times bigger than her daughter. Dad is 2 years older than Mom. How old are each of the family members? Write the result in ascending order and separated by spaces

Let

x> Mon's age

y> Son's age

z> Daughter's age

w---> Dad's age

we know that

x+y+z+w=70 > equation A

x=6y > y=x/6 > equation B

x=10z > z=x/10 > equation C

w=2+x > equation D

substitute equation B, C and D in equation A and solve for x

x+(x/6)+(x/10)+(2+x)=70

Multiply by 60 both sides

60x+10x+6x+120+60x=4,200

136x=4,200-120

x=4,080/136

x=30 years

Find the value of y

y=x/6 > y=30/6=5 years

Find the value of z

z=x/10 > z=30/10=3 years

Find the value of w

w=2+x > w=2+30=32 years

Write the result in ascending order and separated by spaces

3  5  30  32

so

Daughter  Son  Mon  Dad

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
