Answer:
6
Explanation:
4x = 2x + 12 are also same with 2x + 12 = 4x
so, 2x + 12 = 4x. we need to move the 2x besides 4x.
2x is a positive number, so when we moved a positive number, it will automatically be a negative number. We have to change the operation from ' + ' to ' - '. so it will be like this
12 = 4x - 2x
12 = 2x
so, move the 2x to make it easier like this
2x = 12
to find x, we have to move 2. 2x are same with 2 × x. So, if the operation is ' × ', when we moved the number, the operation will be ' ÷ '.
x = 12÷2
so,
x = 6.
6 is the answer.
