Question

—4 = 2t - 2
Solve for t

Answer 1

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

Answer 2

`t=-1`

Explanation:

`-4=2t-2`

`2t-2=-4`

Add 2 to both sides:

`\longmapsto2t-2+2=-4+2`

`\longmapsto2t=-2`

Divide both sides by 2:

`\longmapsto(2t)/(2)=(-2)/(2)`

`\longmapsto t=-1`
