Question

Slove equations with variables on both sides -8c + 6 = -9c

Answer 1

We will investigate how to solve equations involving a single variable.

We have the following equation at hand:

`-8c\text{ + 6 = -9c}`

We will apply basic mathematical operations on the equation above and isolate the variable ( c ) on either side of the " = " sign.

Adding ( 8c ) on both sides of the equation:

`\begin{gathered} -8c\text{ + 6 + 8c = -9c + 8c} \\ (\text{ 8c - 8c ) + 6 = -c} \\ 6\text{ = -c} \end{gathered}`

Then multiply ( -1 ) on both sides of the equation as follows:
