A+A=4 B+B=6 C+C=10 A+B×C=??? please help?
A + A = 4
B + B = 6
C + C = 10
A + B × C
= 2 + 3 × 5
= 2 + 15

You need to clarify
is it (A+B)X C=
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=?
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.
