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.

$\frac{3}{8}x+7=-\frac{7}{8}$

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

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

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:

$\begin{gathered} \frac{3x}{3}=-\frac{63}{3} \\ \\ x=-21 \end{gathered}$

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

$x=-21$
