Question

How do I solve: (3/8)x + 7 = -7/8

Answer 1

To solve the given equation, we need to perform any needed calculation to isolate X on it.

`(3)/(8)x+7=-(7)/(8)`

The first step is to multiply both sides by 8, as follows:

`\begin{gathered} ((3)/(8)x+7)\cdot8=-(7)/(8)\cdot8 \\ \\ 3x+56=-7 \end{gathered}`

Now we subtract 56 to both sides:

`\begin{gathered} 3x+56-56=-7-56 \\ \\ 3x=-63 \end{gathered}`

Now we divide both sides by 3:

`\begin{gathered} (3x)/(3)=-(63)/(3) \\ \\ x=-21 \end{gathered}`

From the solution we developed above, we are able to conclude that the answer of the given equation is:

`x=-21`
