Step-by-step explanation:
15 less than 3 times n is 3n - 15, thus
n + 3n - 15 = 101 ← equation modelling the situation
4n - 15 = 101 ( add 15 to both sides )
4n = 116 ( divide both sides by 4 )
n = 29
Answer:
first you choose one of the varibles to solve for so im going to start with s you would add them up and subtract them that way there on the other side of the = sighs so you equation would be 8+2d+3=-7s then you add the 8 and the 3 and you would get 11+2d=-7s i dont know what you do after this i think this is the answer.
