$x = \frac{90}{7}$ $x = 90/7$ or about $12.857$ $12.857$ (rounded to the nearest thousandth's place)

Explanation:

$\frac{7}{15} x - 4 = 2$ $7/15x - 4 = 2$

To solve for the variable $x$ $x$ , we have to make it by itself. First, add $4$ $color(blue)4$ to both sides of the equation:
$7/15x - 4 quadcolor(blue)(+quad4) = 2 quadcolor(blue)(+quad4)$

$7/15x = 6$

Now multiply both sides by $color(blue)15$ :
$7/15x color(blue)(*15) = 6 color(blue)(*15)$

$7x = 90$

Now divide both sides by $color(blue)7$ :
$(7x)/color(blue)7 = 90/color(blue)7$

Therefore,
$x = 90/7$ or about $12.857$ (rounded to the nearest thousandth's place)

Hope this helps!
