I need to see the statements

Answer 5

3s + 12 = 21 (subtract 12 from both sides)
3s = 21 - 12
3s = 9 (divide both sides by 3)
s = 3

Kendall scored 3 times as many points as Abdul scored in a basketball game. Otis scored 5 more points than Abdul scored. The three players scored 45 points all together. How many points did each player score?
Kendall: 24 points; Abdul: 13 points; Otis: 8 points
Kendall: 8 points; Abdul: 8 points; Otis: 8 points
Kendall: 24 points; Abdul: 8 points; Otis: 13 points
Kendall: 8 points; Abdul: 13 points; Otis: 24 points

Answer 10

K = 3A
O = A + 5

K + O + A = 45
(3A) +( A + 5) + A = 45
5A + 5 = 45
5A = 40
A = 8

K = 3A
K = 3(8) = 24

O = A + 5
O = 8 + 5
O = 13

check...
K + O + A = 45
24 + 13 + 8 = 45
45 = 45 (correct)

Kendall = 24, Abdul = 8, Otis = 13
