Question

solve for b.
784 = 7b
b =
submit

Explanation:

Step1: Isolate the variable \( b \)

To solve for \( b \) in the equation \( 784 = 7b \), we need to isolate \( b \). We can do this by dividing both sides of the equation by 7. The reason for this is that if we have an equation \( a = bc \) (where \( c
eq 0 \)), then \( b=\frac{a}{c} \) by the division property of equality. So, dividing both sides by 7 gives us:
\( \frac{784}{7}=\frac{7b}{7} \)

Step2: Simplify both sides

Simplify the left - hand side: \( \frac{784}{7} = 112 \)
Simplify the right - hand side: \( \frac{7b}{7}=b \) (because any non - zero number divided by itself is 1, so \( \frac{7}{7}b = 1\times b=b \))

Answer:

\( 112 \)
