By arranging the equation

Explanation:

$7 x - \left(2 x - 4\right) = 39$

First get rid of the paranthesis:

$7 x - 2 x + 4 = 39$

$x \left(7 - 2\right) = 39 - 4$

$x \left(5\right) = 35$

$x = \frac{35}{5}$

$x = 7$.

Your solution $x = 7$

$x = 7$

Explanation:

Distribute the negative
$7 x - 2 x + 4 = 39$
Combine like terms
$5 x + 4 = 39$
Subtract $4$ from both side
$5 x = 35$
Divide both sides by 5
$x = 7$
