Answer:
1 - Let the number of marbles parmit have be x.
= x + 5x + 7 = 37
= x + 5x = 37 - 7
= x + 5x = 30
= 6x = 30
= x = 30\6
= x = 5
Answer - Parmit has 5 marbles.
2 - Let the age of Laxmi be x years.
= 3x + 4 = 49
= 3x = 49 - 4
= 3x = 45
= x = 45/3
= x = 15
Answer - Age of Laxmi is 15 years.
Let the number of fruit trees be x.
= 3x + 2 = 77
= 3x = 77 - 2
= 3x = 75
= x = 75 / 3
= x = 15
Answer - The number of fruit trees is 15.
