Estimation for addition: 86 rounds up to 90 and 17 rounds up to 20 so:
90 + 20 = 110
Estimation for subtraction is the same thing but with subtraction
90 - 20 = 70
Now for the exact answers:
86 + 17 = 103
86 - 17 = 69
Your answers are 110, 70, 103, and 69.

Answer:
No Solution
Step-by-step explanation:
<u>-1/7</u>(14+28p)-13=<u>4</u>(1/2p-3)-6p
-2-4p-13=2p-12-6p
rearrange the question so like terms are next to each other
<u>-2-13</u>-4p=<u>2p-6p</u>-12
-15-4p=-4p-12
add 12 to both sides
-3-4p=-4p
add 4p to both sides
-3=0
