    -2t+4+3t=6-7
    1t+4=-1
    1t+4-4=-1-4
    1t=-5
    1t/1=-5/1
    t=-5

    Is that right? It has been a LONG time lolol. I have been workign through a prealgebra book with liam though and i think i did the order correctl?

    I got -5

    -2t +4 +3t= 6-7
    first lets take care of the numbers without the t's
    -2t +4 +3t= -1
    -4 -4
    -2t +3t= -5
    now the -2 and the +3
    +1t or just t= -5

    is that what the book says? pre-algebra was a long time ago but I think I'm right.
