What solution is correct ?
x=

x=400

Step-by-step explanation:

You cannot subtract the 30x from 985 because 985 is not a like term - meaning there is no 'x' attached to 985. Very important - only add/subtract like terms.

So:

30x - 215 = 985

move 215 to the other side because 215 and 985 are similar (they are just regular numbers - no extra variables). To move 215 to the other side you need to perform the same operation to both sides of the equal sign.. that way it cancels out on one side and moves to the other, like so:

(30x - 215)+215 = 985+215

=> 30x = 1200

Now we need to find x, not 30 x, so since 30 is being multiplied by x, to get it the other side we need to divide it out..

(30x)/30 = (1200)/30

x = 400

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.

your answer would be 12
