1. Line 3 is the first error. In order to get rid of the 25, you add it to both sides, not subtract. So, your answer is B.
2. Line 1 because it says in the question "4
less than a number" and the equation adds 4, instead of subtracting. Your answer is A.
3. Line 4. To get rid of the 6 in front of 6x, you have to divide by it, but instead they multiply. So, your answer is C.
4. To solve this, you will use the distributive property first:
![4(x-3)=16](https://tex.z-dn.net/?f=4%28x-3%29%3D16)
Turns into:
![4x-12=16](https://tex.z-dn.net/?f=4x-12%3D16)
Get rid of the 12:
![4x=28](https://tex.z-dn.net/?f=4x%3D28)
Divide by 4:
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
Your answer is B.
5. You have to set it up:
![\frac{x}{3} = -11+4](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3%7D%20%3D%20-11%2B4%20)
Just solve for x:
![\frac{x}{3} = -7](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3%7D%20%3D%20-7%20)
Multiply both sides by 3 to isolate x:
![x = -21](https://tex.z-dn.net/?f=x%20%3D%20-21)
Your answer is B.
