Solve the equation $8b + 4 = 20$ by finding the missing term and simplifying the fraction.

STEP 1

Assumptions1. The given equation is $8b +4 =20$ . We are solving for $b$

STEP 2

First, we need to isolate $8b$ on one side of the equation. We can do this by subtracting $4$ from both sides of the equation.
$8b +4 -4 =20 -4$

STEP 3

implify the equation to find the value of $8b$ .
$8b =20 -$

STEP 4

Calculate the value on the right side of the equation.
$8b =16$ This fills in the first missing term in the problem, $\square =16$ .

STEP 5

Now, we need to solve for $b$ . We can do this by dividing both sides of the equation by $8$ .
$\frac{8b}{8} = \frac{16}{8}$

STEP 6

implify the equation to find the value of $b$ .
$b = \frac{16}{8}$

STEP 7

Calculate the value of $b$ .
$b =2$ So, the solution to the equation is $b =2$ .
