$3 x = \frac{3}{2}$ $3x = 3/2$

$3 x - 2 + 5 x = 2$ $3x - 2 + 5x = 2$

Before we find the value of $3 x$ $3x$ , let's first find the value of $x$ $x$ .

To do so, first combine $3 x + 5 x$ $3x + 5x$ :
$8 x - 2 = 2$ $8x - 2 = 2$

Add $2$ $color(blue)2$ to both sides of the equation:
$8x - 2 quadcolor(blue)(+quad2) = 2 quadcolor(blue)(+quad2)$

$8x = 4$

Now divide both sides by $color(blue)8$ :
$(8x)/color(blue)8 = 4/color(blue)8$

$x = 1/2$

Since we want $3x$ , let's multiply that by $color(blue)3$ :
$1/2 color(blue)(*3) = 3/2$

Hope this helps!
