Answer 1

Answer:

Step-by-step explanation:

1) Father's age =x, son's age= y

x+y=40 & x=3y

2) x-y=26

y=3x

3) x+y=180

y=x+18

4) 4x+7y=2100

5x+2y=1750

Answer 2

Answer:

Step-by-step explanation:

x+y=40   y = 3 x

x-y=26      x=3y

x+y=180       y=x+18

4x+7y=2100      5x+2y=1750

x + y = 39       2x +4y =132
