Gregory’s age is 5 years greater than of Amanda’s age. Gregory is 17 years old. If Amanda’s age is denoted by x, which equation represents this situation and how old is Amanda?
Let Amanda's age = x.
Gregory's age = x + 5.
Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12
Amanda is 12 years old.
Amandas Age.
Amanda=x
Gregorys Age.
Gregory=17 yrs.
Equation formation.
1/3× x = (1/3 x)
1/3 x + 5 = 17
Equation= 1/3 x +5 =17
1/3 x = 17-5
1/3 x = 12
x=12×3
x=36
Amanda`s age = 36
