Answer:
x = 6
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
5x = 3x+12
Subtract 3x from each side
5x -3x = 3x+12-3x
2x= 12
Divide by 2
2x/2 = 12/2
x = 6
Answer:
Step-by-step explanation:
Shobo's age = x years
His mother's age = 6 times of
Shobo's age
= 6x years
Five years from now
________________
Shobo's age = ( x + 5 ) years
According to the problem given,
x + 5 = one by third of his mother's
present age
x + 5 = 6x / 3
x + 5 = 2x
5 = 2x - x
5 = x
Therefore ,
Shobo's present age = x = 5 years
His mother's age = 6x
= 6 × 5
= 30 years
