Question

Solve each equation for the unknown

1. 5 + y = 7.
2. 3.8 = a + 2.5
5. + p = 9 1/3 ​

Answer 1

1. Y=2


2.A=1.3



5.p=28/3

Answer 2

1. 5 + y = 7

⇒ y = 7 - 5

⇒y = 5

2. 3.8 = a + 2.5

⇒ a = 2.5 - 3.8

⇒ a = -1.3

3. 5 + p = 9 1/3 ​

⇒ p = 9 1/3 - 5

⇒ p = 28/3 - 5

⇒ p = 28/3 - 15/3

⇒ p = 13/3

⇒ p = 4 1/3
