Question

How do you solve for y
`(y)/(2) - 3.1 = 15.9`

Answer 1

Given:

An equation

`(y)/(2)-3.1=-15.9`

To solve:

We have to solve for y.

Solution:

Add 3.1 on both sides.

`\begin{gathered} (y)/(2)-3.1+3.1=-15.9+3.1 \\ (y)/(2)=-12.8 \end{gathered}`

Multiply by 2 on both sides:

`\begin{gathered} (y)/(2)\cdot2=2(-12.8) \\ y=-25.6 \end{gathered}`

Thus, the answer is y = -25.6.
