PLZ HELP IM ON A TIMER I WILL GIVE BRAINLIEST

Step-by-step explanation:

will be 3 or 4 because 9 x 2 is 18 plus 3x2 equals 24 and 12 x 2 is equal to 24 and -2 and negative -3 add those together and u have -5 so now your basically doing 24 - 5 y but idk how they do it in your lesson so its 3 or 4

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
