Answer:
Answer is 2a + 8 because 2 times a is 2a and 2 times 4 is 8
Remember you can do anything to an equaiton as long as you do it to both sides
-x=4-3x
add 3x both sides
3x-x=4+3x-3x
2x=4+0
2x=4
divide 2
2x/2=4/2
2/2x=2
1x=2
x=2
Answer:

Super simple
So he wants to be three pounds away from his ideal weight (168)
Which means he can either be 3 pounds under or 3 pounds over
So his min is 165, his max is 171
