Penny solved an equation by subtracting 6 from each side of the equation and then divided each side by 5. Which of these could have been the equation Penny solved?

A. 1/5x+6=11 B. 5x-6=11

C. 5x+6=21 D. 6x+5=17

Step-by-step explanation: C

To get the variable, x, alone, you need to subtract the only other number on that side of the equation, which is 6. Then, to even it out you have to subtract 6 from the other side as well. You are left with 5x=15. The final step, to get a naked x, is to divide both sides by 5.
