Answer:
x = 8
Explanation:
For example, if you have a value for y, you can solve for x. If y is 20, then you can find x by rearranging the equation
(assuming that y is 20)
20 = x + 12 same as y = x + 12
Subtract 12 from both sides
x = 20 - 12
x = 8
8 is not the final answer because I do not know the value of (y)
