Question

2t+7=-1 inverse the term without variable

Answer 1

Simplifying:
2t+-7=1

Reorder the terms:
-7+2t=1

Solving variable for "t."

Move all terms containing "t" to the left

Add "7" to each side of the equation
-7+7+2+=1+7

Combine the terms
-7+7=0
0+2+=1+7
2t=17

Combine the like terms:
1+7=8
2t=8

Divide each side by 2. You now have: t=4

Good luck, hope this helped! :)
