    A + A = 4

    B + B = 6

    C + C = 10

    A + B × C

    = 2 + 3 × 5

    = 2 + 15

    = 17

    You need to clarify

    A+BXC=

    is it (A+B)X C=

    or

    A+(BXC)=

    the latter is the default order taken by computers, which do you mean?

    A has to be 2, B has to be 3 and C has to be 5. There are no other values that will work.

    Proof: A+A= 4 is the same as 2A = 4 4 divided by 2 = 2.

    2+3*5 = 17 Due the multiplication first.

    A+A is the same as saying 2A, B+B is the same as saying 2B, and C+C is the same as saying 2C.

    2A=4, 2B=6, 2C=10

    In each of these expressions you can divide both sides by 2

    A=2, B=3, C=5

    Now that you know what each variable is equal to, you can plug these values in for the expression A+B*C=?

    2+3*5=17

    A+B*C=17

    Remember to follow order of operations and do 3*5 first so you don't end with (2+3)*5, which would be 25.

    2 + 3 × 5 = 17

    I assume that the question was designed to drive home the point that adding a number to itself is the same as multiplying by two.
