you need to simplify the equation by combining elements with the same variable. if it's just a letter, it's 1*the variable. You also combine numbers.

clear the negative things from your mind and you will have room to absorb the new material more easily.

you are here to learn and we cannot give direct answers. you need to read the responses given and ask questions about what you do not understand.

  • BunnyKitten02
ok so how can i solve these quickly because this is due soon
triciaal
  • triciaal
once you learn something practice and you will be able to do the problems faster. this is basic stuff for higher math. all the best.
triciaal
  • triciaal
for now just look at what the question is asking and identify what needs to be done seems like all you are doing right now is grouping like terms
BunnyKitten02
  • BunnyKitten02
i have like 15 minutes
