6y+4=8+2y+2y
Combine like terms
6y+4=8+4y
Get like terms on the same side, subtract 4 from both sides to get
6y=4+4y
Subtract 4y from both sides to get
2y=4 IS the answer (even though it can be simplified further, that answer isn't one of the choices so 2y=4 is the equation simplified.)

Step 2 was the mistake when you distribute a number you don't add (which is what they did to get 5x) you multiply to get 6x. So the correct step 2 would be
6x-8=12+2x
Becuase of the distributive property.
Hope this helped!
Answer:
n(-9+ n) =0
Step-by-step explanation:
-9n+n^2=0 Kind of use 'reverse distributive' property
n (-9 + n) = 0
The vertical scale reads calories per minute, so we're interested in where the red line on the graph crosses the horizontal line at 15 calories per minute. That crossing point is more than halfway between 150 and 200 (pounds?) of weight. The only suitable choice from offered answers is
.. 180 lbs, the 3rd selection.
The correct volume is 56 in^3
