You Simplify both sides of the equation.
8
(
1−
5x
)
=13
Simplify:
(8)
(1)
+
(8)
(
−
5x
)
=13
(Distribute)
8+
−
40x
=13
−
40x
+8
=13
Step 2: Subtract 8 from both sides.
−
40x
+8
−8
=
13−8
−
40x
=5
Step 3: Divide both sides by -40.
−
40x/
−40
=
5/
−40
x=
−1/
8

Perform indicated multiplications on left side.
8-40x=13 subtract 8 from both sides
-40x=5 divide both sides by -40
x=-5/40
x=-1/8
Note: There are no mixed numbers in this problem.
