-7 and 1
Because if you do -7 plus 3 which equals -4 and the absolute value of negative 4 is 4. And 1+3 is 4
So I'm not 100% on this, but I believe that first you need to combine like terms. The 4x and the -2x make 2x and distribute the 2 so you get 2x+1. That all equals 2x+5=2x+2. You need to get the variable by themselves so I will minus the 2. You then get 2x+3=2x. You then need to minus the 2x, which makes 0. So the answer is 3=0, or undefined. Is that about what you guys are working on? Have you learned about undefined?
Sandy would probably take just as long as her mother because it says their mother takes 5 hours if decorating the house alone so if sandy is doing it alone it would also probably take her 5 hours as well. If this is wrong I’m sorry.
