Answer:
pls mark as brainliest
Step-by-step explanation:
llet sudhakar age be x
son y
x=4+y
after 8 years
x+8=8+4+y
x+8=12+y
x-y=4
Answer:
The suitable pair of linear equations for the data is y = 9x+4 and y+8=4(x+8)
Step-by-step explanation:
Consider the provided information.
Let the present age of Sudhakar's son is x
The present age of Sudhakar is 4 more than 9 times of his son's age.
Let Sudharkar present age is y.
y = 9x+4
It is given that given that 8 years later the age of Sudhakar will be 4 times of his son's age.
y+8=4(x+8)
Substitute the value of y in above equation.
9x+4+8=4(x+8)
9x+12=4x+32
5x=32-12
x=4
Hence, the present age of Sudhakar's son is 4 and present age of Sudharkar is 40.
The suitable pair of linear equations for the data is y = 9x+4 and y+8=4(x+8)
