=

9-5 \frac{7}{8}=x-\frac{1}{8}

Simplify Left Side:
First, simplify the left side of the equation.
\newline
Calculate
5
(
7
)
/
8
=
35
/
8
5(7)/8 = 35/8
5
(
7
)
/8
=
35/8
.
\newline
Now,
9
−
35
/
8
=
72
/
8
−
35
/
8
=
37
/
8
9 - 35/8 = 72/8 - 35/8 = 37/8
9
−
35/8
=
72/8
−
35/8
=
37/8
.
Rewrite Equation:
Next, rewrite the equation with the simplified left side.
\newline
37
8
=
x
−
1
8
\frac{37}{8} = x - \frac{1}{8}
8
37
=
x
−
8
1
.
Solve for x:
Now, solve for x by adding
1
8
\frac{1}{8}
8
1
to both sides of the equation.
\newline
37
8
+
1
8
=
x
\frac{37}{8} + \frac{1}{8} = x
8
37
+
8
1
=
x
.
\newline
38
8
=
x
\frac{38}{8} = x
8
38
=
x
.
Final Simplification:
Finally, simplify
38
8
\frac{38}{8}
8
38
to get
x
x
x
.
\newline
38
8
=
4.75
\frac{38}{8} = 4.75
8
38
=
4.75
.
