Choose the best translation for the sentence:
The product of a number and 5 is -25.

•  $n\cdot5=-25$  

•  $5n=-25$  

•  $n\div5=-25$  

• both a and b

Which of the following describes the best method for solving the equation:

 $-7n+5=-26$  

• Subtract 5 from both sides; then multiply both sides by -7

• Add 5 from both sides; then add 7 to both sides

• Subtract 5 from both sides; then divide both sides by -7

• Add 5 from both sides; then divide both sides by -7
