6 + x=18 how do you solve problems like these?

the answer of 6 + x = 18 is x = 12

Step-by-step explanation:

In order to solve the problem, you have to do the following: you have to subtract on both sides by 6 minus 18, the value is 12, so when you have finished subtracting 18 minus 6, lower the X and then you have the equivalent of X, which is X = 12.

6 + x = 18

-6 - 6 cancel 6-6 and subtract 18-6

that the answer is x = 12 and so you get the value of x.
