You will have to get the -3x by itself so you will add 6 to both sides so -3x-6+6-5+6 and you will get -3x=11do you need anymore help?
Step-by-step explanation:
He goes 20 miles in total so knowing that you can multiply 20 by 6 which is 120. Then you can add the break on giving you 125 min.
(12 x 16) = 192 + 8 = 200
Therefore the answer is 200 which when divided by 12 gives a quotient of 16 and a remainder of 8.
