The mean is just the arithmetic average:
(103+99+90+86+105+96+x)/7=95
(579+x)/7=95
579+x=665
x=86

4(2.53(207))
Since there are no equations in the parentheses, or exponents, we skip these, and head straight for multiplication:
4(523.7)
Then, do multiplication again:
2094.8
So that means, 4(2.53(207)) = 2094.8
I assume the brackets mean parentheses, since the absolute value of 523.7 does not mean anything in this equation.
