Question

Here is an equation.

a+b=c
Given that: a, b and c are different single-digit numbers,
a, b and c are all even,
a, b and c are all positive,
a = 4,
find the numbers b and c to make the equation true.

Answer 1

Explanation:

Answer

2 and 8

Answer 2

Answer: B=2, C=6

Explanation:

Even single-digit numbers: 2, 4, 6, 8

A+B < 10

4+B < 10

B < 6

The choices are 2 and 4, but since they are different single-digit numbers and that A is 4, B has to be 2.
4+2=6.
