Answer:
-9t+9
Step-by-step explanation:
1. Review given problem [tex]\left(-3t+3\right)+\left(2-2t\right)+\left(-4t+4\right)[/tex]
2. Remove parentheses [tex](a)=a[/tex]
[tex]=-3t+3+2-2t-4t+4[/tex]
3. Group like terms
[tex]=-3t-2t-4t+3+2+4[/tex]
4. Add similar elements: [tex]-3t-2t-4t=-9t[/tex]
[tex]=-9t+3+2+4[/tex]
5. Add the numbers: [tex]3+2+4=9[/tex]
[tex]=-9t+9[/tex]
[tex]=9 (1 - t)[/tex]
[tex]=9 - 9 t[/tex]
[tex]=-9 (t - 1)[/tex]
I tried making this one more organized, took a little longer but much more understandable.
