Answer:
x = -2
x = 2
x = ?/2
x = ?(2)
Step-by-step explanation:
For each problem you want to isolate the variable.
For x + 2 you want to move the 2 by subtracting it (since it is being added to the x) from each side. Assuming the other side of the equal sign is 0, the answer is -2.
Same thing for x - 2, isolate by adding the 2 (since it is being subtracted).
For 2x and x ÷ 2 it is a little different. If we assume the opposite side is 0, the answer will be 0 because 0 divided or multiplied by 2 will give you 0. But if the opposite side is a different number, the answer will be that number and then the respected equation for the problem (divide both sides by 2 in 2x because the x is being multiplied by the 2 and multiple both sides by 2 in the x ÷ 2 because the x is being divided by the 2).
