Answer:

[tex]t=-1[/tex]

Step-by-step explanation:

[tex]-4=2t-2[/tex]

[tex]2t-2=-4[/tex]

Add 2 to both sides:

[tex]\longmapsto2t-2+2=-4+2[/tex]

[tex]\longmapsto2t=-2[/tex]

Divide both sides by 2:

[tex]\longmapsto\frac{2t}{2}=\frac{-2}{2}[/tex]

[tex]\longmapsto t=-1[/tex]

_______________________
Add 2 to both sides to get -2=2t then divide both sides by 2 to get t=-1
