Simplify
2b13−2
Reduce fractions to a common denominator
2b13−2b2×2b
Write all numerators above the common denominator
2b13−2×2b
Multiply the terms
2b13−4b
2b13−4b=0
Cross multiply
13−4b=2b×0
Simplify the equation
13−4b=0
Move the constant to the right side
−4b=0−13
Removing 0 doesn't change the value,so remove it from the expression
−4b=−13
Change the signs on both sides of the equation
4b=13
Divide both sides
44b=413
Divide the numbers
b=413
Check if the solution is in the defined range
b=413,b=0
Solution
b=413
Alternative Form
b=3.25
