Çözüldü Two-Variable Equations (6th Grade Level on This Site)

The sum of the integers p and q is 495. If p is divided by 10, the result is equal to q. What is the value of p ?

A) 40
B) 45
C) 245
D) 250
E) 450

p + q = 495....(I)
p / 10 = q....(II)
Substituting the term at the left side of the equation (II) for its place in (I);
p + p / 10 = 495 ⇒ 11p = 10·495 ⇒ p = 10·45 = 450.
