This is something new for us and my teacher didn’t really explain how to do it

Step-by-step explanation So the first thing that you are going to want to do is subtract, subtract, multiply, or divide by the number that gives you the best answer i hope this helped ~TACC

Step-by-step explanation: I think they mean that your supposed to to it backwards, example on the first problem you take 54-29 instead of 29+d=54 so you get 25 and you do it backwards on each problem, example number two on the second problem you take 45-35 to get the answer n= 10 and the third problem you take 30/6 to get w=5. So you basically take the opposite of the sign
