First add 2 to both sides, next add 2 + 3 to get 5, next break down the equation into two problems which would be 2x - 5 = 5 and -(2x - 5) = 5, NOT 2x - 5 = -5, so this is the FIRST incorrect step, while step 4 is incorrect because its suppose to be 2x = 5 not 10, that's the second step, not first so answer is:
Answer: A) Step 3.
If you are looking for gallons then its 0.0625
Answer:
A.x+5=6x
Step 1:subtract 6x from both sides.
x+5-6x=6x-6x
-5x+5=0
Step 2:subtract 5 from both sides.
-5x+5-5=0-5
-5x=-5
Step 3:divide both by -5
-5x/5=-5/5
X=1
