Answer:
x = 10
Explanation:
this is because if we look at the equation and do the opposite of addition (subtraction) we will have an equation that looks like this
16 - 6 = x
with this info we can now infer that 16 - 6 will give us a sum of 10
16 - 6 = 10
x = 10
we can as well as check our answer by plugging in the 10 into our original equation
10 + 6 = 16
which will give us the correct mathematical equation
