Hey there!
The answer is most likely option A
Because,
First, we have to add by [tex]5 [/tex] on each of your sides!
Like: [tex] \frac{1}{3}x - 5 + 5 \\ \\ y + 5 [/tex]
We get this as our answer for this portion: [tex] \frac{1}{3}x = y + 5 [/tex]
Nextly, we have to divide by [tex] \frac{1}{3} [/tex] on each of your sides
Like: [tex] \frac{1/3x}{1/3} = \frac{y +5 }{1/3} [/tex]
Therefore your answer would be: [tex]x = 3y + 15 [/tex]
Good luck on your assignment and enjoy your day!
