My algebra....

I have learned so much this week! :)

I am now solving with parentheses, I am not asking you to do the work
for me as some lady posted-but could someone give me directions?

2m - 3 (m + 3) = -13

I am stumped. I kept getting it wrong, the book says the answer should be 4.

  • distribute the -3 (multiply it times both items in the parentheses):
    2m -3m -9 = -13
    add 9 to both sides:
    2m -3m = -4
    Combine the m's (add them together):
    -1m = -4
    divide both sides by -1:

  • remember that when you have to move the number without the coefficient to the other side that you're having to add it -9+9 = 0
    -13+9= -4 and 2m-3m = -1m so when you get there, divide by the -1 on both sides, which just gives you m=4 ta da!
