Solve for x 7x-4y=28

$7 x - 4 y = 28$

Step 1

Add $4 y$ to both sides of the equation.

$7 x = 28 + 4 y$

Step 2

Divide each term in $7 x = 28 + 4 y$ by $7$ and simplify.

Divide each term in $7 x = 28 + 4 y$ by $7$ .

$\frac{7 x}{7} = \frac{28}{7} + \frac{4 y}{7}$

Simplify the left side.

Cancel the common factor of $7$ .

Cancel the common factor.

$\frac{7 x}{7} = \frac{28}{7} + \frac{4 y}{7}$

Divide $x$ by $1$ .

$x = \frac{28}{7} + \frac{4 y}{7}$

Simplify the right side.

Divide $28$ by $7$ .

$x = 4 + \frac{4 y}{7}$
