What is the answer to -t plus 9 equals t plus 5?

Answer 1

-t + 9 = t + 5

(if it helps, you can pretend there is a 1 in front of each t)

-1t + 9 = 1t + 5

Add 1t to both sides

-1t + 1t + 9 = 1t + 1t + 5

(Keep the variable on the left of the equals sign lessens confusion, so let's flip the terms)

9 = 2t + 5

2t + 5 = 9

Subtract 5 from both sides

2t + 5 - 5 = 9 - 5

Divide both sides by 2

2/2t = 4/2

t = 2
