Solve the equation for y. 5x+2Y=9

x = -2/5(y) + 9/5

Step-by-step explanation:

since you're solving for x, you should seperate x from the other things, so you should move the 2y to the other side, making it opposite, which will get you 5x=-2y+9. Then you divide both sides by 5, 5x divided by 5 is x,  -2y divided by 5 is -2/5(y), and 9 divided by 5 is 9/5. Put that together and you get

x =-2/5(y)+9/5

just sum

10 + 10 = 20

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
