You want to get x by itself, so you need to get rid of the division on the left side of the equals sign. The way to undo division is to multiply. So, multiply both sides of the equation by 2. This gives you x = 2.4, so now you have your answer.
Now, since the problem wants us to check our answer, we just put 2.4 back into the equation as x. This gives us 2.4 / 2 = 1.2. Now, we just simplify to see if the equation is true. If it is true, the answer is correct. 2.4 divided by 2 is 1.2, so 1.2 = 1.2, which means our answer is correct.
The first step should be to isolate x or get x alone. This means we should get rid of the divided by 2 on the left by multiplying both sides by 2. This would get us to 2 * X/2 = 1.2 * 2. The multiplying X/2 would simplify to just X, and the 1.2 * 2 = 2.4. Therefore the final equation would become X = 2.4.
To check, you would plug in 2.4 into where X is in X/2 = 1.2. Since 2.4/2 = 1.2, we know that X = 1.2 from checking.
