Solve each equation for the unknown
1. 5 + y = 7.
2. 3.8 = a + 2.5
5. + p = 9 1/3 ​

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

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
