It appears you have the system with augmented matrxi ...
Right away, you notice that the 4th row is 3 times the 2nd row, so the equations are dependent and will not have a unique solution.
My calculator tells me the reduced equations can be written
... x1 -14x3 -19x4 = -8
... x2 -12x3 -16x4 = -7
This says there are two dependent equations in the set, not just one.
Answer:
Here is your answer
Step-by-step explanation:
Step -1: Forming equations.
Let, present age of son = x
And, present age of father = 3x+3
3 years later, age of son = x+3
age of father = 3x+3+3=3x+6 ...(i)
According to the given condition, age of father = 10+2(x+3) ...(ii)
Step -2: Solving for x
From (i) and (ii)
∴3x+6=10+2(x+3)
⇒3x+6=10+2x+6
⇒3x−2x=10+6−6
⇒x=10
∴Present age of son = 10
and present age of father = 3x+3=3×10+3=33
Hence, son’s present age is 10 years and father’s
