Solve each equation for the unknown <br>1. 5 + y = 7.<br>2. 3.8 = a + 2.5<br>5. + p = 9 1/3 ​
Alexxandr [17]

Answer:

1. 5 + y = 7

⇒ y = 7 - 5

⇒<u>y = 5</u>

2.  3.8 = a + 2.5

⇒ a = 2.5 - 3.8

⇒ <u>a = -1.3</u>

3. 5 + p = 9 1/3 ​

⇒ p = 9 1/3 - 5

⇒ p = 28/3 - 5

⇒ p = 28/3 - 15/3

⇒ p = 13/3

⇒<u> </u><u>p = 4 1/3</u>
