Sam earned $450 during winter vacation. he needs to save $180 for a camping trip over spring break. he can spend the remainder of the money on music. write an inequality to show how much he can spend on music.

180+x=450 idk if this is wrong

180 greater than or equal to 450 - m

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
