Answer:
16
Step-by-step explanation:
let the smaller no be x so the greater no is 8 + x
soln
8+x + x = 40
8 + 2x = 40
2x = 40-8
2x = 32
x = 32÷2
therefore x = 16
Answer:
16 and 24
Step-by-step explanation:
let the 2 numbers be x and y, x > y , then
x + y = 40 → (1)
x = y + 8 → (2) [ greater number 8 more than smaller ]
Substitute x = y + 8 into (1)
y + 8 + y = 40, that is
2y + 8 = 40 ( subtract 8 from both sides )
2y = 32 ( divide both sides by 2 )
y = 16
Substitute y = 16 into (2)
x = 16 + 8 = 24
The 2 numbers are 16 and 24
