a = first number
b = second number
b = a + 9
a + b = 25
a + a + 9 = 25
2 a + 9 = 25 Subtract 9 to both sides
2 a + 9 - 9 = 25 - 9
2 a = 16 Divide both sides by 2
a = 16 / 2 = 8
b = a + 9 = 8 + 9 = 17
First number = 8
Second number 17
b = second number
b = a + 9
a + b = 25
a + a + 9 = 25
2 a + 9 = 25 Subtract 9 to both sides
2 a + 9 - 9 = 25 - 9
2 a = 16 Divide both sides by 2
a = 16 / 2 = 8
b = a + 9 = 8 + 9 = 17
First number = 8
Second number 17
