Answer:
The number of Jack's stamps is 33 and Dylan's stamps is 13
Explanation:
Let
x -----> the number of Jack's stamps
y -----> the number of Dylan's stamps
we know that
x+y=46 ----> equation A
x=y+20 -----> equation B
Solve by substitution
substitute equation B in equation A and solve for y
(y+20)+y=46
2y=46-20
2y=26
y=13 stamps
Fond the value of x
x=y+20 -----> x=13+20=33 stamps
therefore
The number of Jack's stamps is 33 and Dylan's stamps is 13
