2 + 5.8 = 6 why is this incorrect

This is incorrect because 2 + 5.8 = 7.8. And 7.8 does not equal 6. 2 + 4 = 6 is the correct answer. This could be represented by this:

2 + x = 6.

Subtract two from both sides to get:

x = 4.

When substituted back into the equation:

2 + (4) = 6.

6

Step-by-step explanation:

Because you add 5.8

+ 2

6.0

you add 8+2=10 you put the zero and then you add the 1 to the 5 and is = 6
