  2. what did you try as a first step (hint: how about distribution?)

    3(q-5)=2(q+5)
    3q-15=2q+10

    ... can you hop on the algebra roller-coaster now??

  6. I'm having trouble with #24 pg 106. I don't know whether to distribute the- 3g or something else.

  7. In #46, if the perimeters are equal, then:

    (2x+4)+(2x+3)+2x=2x+2x+(3x+1)
    Combine Like Terms
    6x+7=7x+1
    Sub 6x fbs
    7=x+1
    Sub 1 fbs
    x=6

    In #24:

    (g+4) - 3g = 1+g
    simplify CLT (3g is being subtracted!)
    -2g+4=1+g
    Add 2g tbs
    4=1+3g
    Sub 1 fbs
    3g=3
    g=1
