Answer:
One solution
Step-by-step explanation:
<em><u>To find the amount of solutions, you must solve first:</u></em>
-8 + t = -t + 10
<em><u>First, add t to both sides:</u></em>
-8 + 2t = 10
<em><u>Add 8 to both sides:</u></em>
2t = 18
<em><u>Divide both sides by 2:</u></em>
t = 9
<u>Since there has been a solution to this equation, that means there's only one solution.</u>
