Question

how do you solve for y$\frac{y}{2} - 3.1 = 15.9$

Answer 1

Given:

An equation

$\frac{y}{2}-3.1=-15.9$

To solve:

We have to solve for y.

Solution:

Add 3.1 on both sides.

$\begin{gathered} \frac{y}{2}-3.1+3.1=-15.9+3.1 \\ \frac{y}{2}=-12.8 \end{gathered}$

Multiply by 2 on both sides:

$\begin{gathered} \frac{y}{2}\cdot2=2(-12.8) \\ y=-25.6 \end{gathered}$

Thus, the answer is y = -25.6.
