Let the two numbers be x and y
then x+y=9
x-y=3
2x=12
x=6
6+y=9
y=3
so the numbers are 9 and 3
Answer:
x = 21
Step-by-step explanation:
Multiply both sides by 16
3/4 x 16 = x - 9
2 Simplify 3/4 x 16 to 48/4
48/4 = x - 9
3 Simplify 48/4 to 12
12 = x - 9
4 Add 9 to both sides.
12 = x - 9
5 Simplify 12+9 to 21
21=x
6 Switch sides.
