Solve for x (40x)÷10=28

$40 x \div 10 = 28$

Step 1

Cancel the common factor of $40$ and $10$ .

Factor $10$ out of $40 x$ .

$10 (4 x) \div 10 = 28$

Cancel the common factors.

Factor $10$ out of $10$ .

$10 (4 x) \div 10 (1) = 28$

Cancel the common factor.

$10 (4 x) \div 10 \cdot 1 = 28$

Rewrite the expression.

$\frac{4 x}{1} = 28$

Divide $4 x$ by $1$ .

$4 x = 28$

Step 2

Divide each term in $4 x = 28$ by $4$ and simplify.

Divide each term in $4 x = 28$ by $4$ .

$\frac{4 x}{4} = \frac{28}{4}$

Simplify the left side.

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4 x}{4} = \frac{28}{4}$

Divide $x$ by $1$ .

$x = \frac{28}{4}$

Simplify the right side.

Divide $28$ by $4$ .

$x = 7$
