Jamil, Kiera and Luther collect badges,
Janil has x badges.
Kicra has 12 badges more than Jamil
Luthier lias 3 times as many badges as Kiera.
Altogether they have 123 badges.
Form an equation and solve it to find the value of x.

Answer 1

Janil: x
Kicra: x + 12
Luthier: 3( x + 12)
x + x + 12 + 3( x + 12) = 123
2x + 12 + 3x + 36 = 123
5x + 48 = 123
5x = 75
X = 15
