The answer is 26. Simply add up all of the numbers arithmetically like you would for two plus two. To make sure the answer is correct, check your work using a calculator.
If it is 3x2 + 4 = 2x + 4, then you can subtract 4 from both sides, and get 3x2 = 2x, and then x = 2/3

It is difficult to say because of uncertainty as to what xx-4 represents. x2 - 4 = 4 gives x2 = 8 so x = ± 2*sqrt(2)
2+2+4 = 8
3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 + 8 + 6 + 0.3 + 4 + 2 = 49.6
The answer to 2 plus 4- will be -2.(i.e) 2+(-4)= 2-4 => -2
