Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<u><em>13x+1+7x+19</em></u>
<u><em>Combine Like Terms:</em></u>
<u><em>=13x+1+7x+19</em></u>
<u><em>=(13x+7x)+(1+19)</em></u>
<u><em>=20x+20</em></u>
Ignore the triangle on the top. i am sure that the correct answer.
Step-by-step explanation:
3x + 5x - 2t = 8
3 . (-1) + 5 . (-1) - 2t = 8
-3 - 5 - 2t = 8
-8 - 2t = 8
-2t = 8 + 8
-2t = 16
t = 16/-2
t = -8
