84 \cdot n = 420

$84 \cdot n = 420$

Step 1

Divide each term in

84 \cdot n = 420

$84 \cdot n = 420$ by

84

$84$ .

\frac{84 \cdot n}{84} = \frac{420}{84}

$\frac{84 \cdot n}{84} = \frac{420}{84}$

Step 2.1.1

Cancel the common factor.

\frac{84 \cdot n}{84} = \frac{420}{84}

$\frac{84 \cdot n}{84} = \frac{420}{84}$

Step 2.1.2

Divide

n

$n$ by

1

$1$ .

n = \frac{420}{84}

$n = \frac{420}{84}$

n = \frac{420}{84}

$n = \frac{420}{84}$

n = \frac{420}{84}

$n = \frac{420}{84}$
