Answer:
t = -13/2 = -6.5
Step-by-step explanation:
-(t + 3) - 10 = -6.5
<em>To find the opposite of t + 3, find the opposite of each term. (-t and -3)</em>
-t - 3 - 10 = -6.5
<em>Subtract 10 from −3 to get −13.</em>
-t - 13 = -6.5
<em>Add 13 to both sides.</em>
-t = -6.5 + 13
<em>Add −6.5 and 13 to get 6.5.</em>
-t = 6.5
<em>Multiply both sides by −1.</em>
t = -6.5. You could also say t = 13/2 or 6 1/2.
