Magic lines
Can you put the numbers 2 to 8 in the circles so that every line
adds up to 15? You can use each number only once.

Answer:

Please see attached image

Step-by-step explanation:

The numbers on the upper row should be:  7   6   2

the number in the central disk should be    5

the bottom row should read  : 8   4   3

The addition on top row: 7 + 6 + 2 = 15

the addition on bottom row:  8 + 4 + 3 = 15

the addition on the central vertical column: 6 + 5 + 4 = 15

diagonal going down:    7 + 5 + 3 = 15

diagonal going up:   8 + 5 + 2 = 15
