In the equation 2(x+5) = 2x +5
You need to use distributive property so your answer would be 2x + 10.
So the mistake that was made is...
B: 2 was not multiplied by 5
5(x-8)-(x+6)=18
5x-40-x-6=18
4x-46=18
4x=18+46
4x=64
x=16
not sure if this is correct but i hope it helps!!!

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3^3+14*y-(25*y-13)-(y+7*y-9*y)=0
Equation at the end of step 1
((3³ + 14y) - (25y - 13)) - -y = 0
Pull out like factors :
40 - 10y = -10 • (y - 4)
Equation at the end of step3:
-10 • (y - 4) = 0
STEP4:
Equations which are never true:
Solve : -10 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
Solve : y-4 = 0
Add 4 to both sides of the equation :
y = 4
