3x = 3/2

Explanation:

3x - 2 + 5x = 2

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

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

Add 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!
