Question

For which equation would x = 5 be a solution?8 x = 8545 ÷ x = 9x + 4 = 54x - 7 = 12

Answer 1

We have x = 5

Check the options:

- 8 x = 85

`\begin{gathered} 8(5)=85 \\ 40\\e85 \end{gathered}`

x = 5 is not a solution

- 45 ÷ x = 9

`\begin{gathered} (45)/(5)=9 \\ 9=9 \end{gathered}`

x = 5 is a solution

Answer: 45 ÷ x = 9
