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.
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  Answer:x=−1/8
