How do you describe a linear equation whose value is equal to or greater than 4.

You would place the circled above the 4 with the inside bubbled in to represent the "equal to" part of the equation. Then you draw an arrow headed towards the right of the number 4 to represent all the numbers that fit the equation.

What is X when 3x+4=10

The answer is 2. If you subtract the 4 from both sides you end up with 3x=6, then you divide both sides by the 3 and get x=2. If you plug in the 2 to the original equation, the results should match A=A
