Answer:
x = 0.75 and or x = -0.38
Explanation:
If the minus sign after the x was on purpose or if you accidentally put the addition sign after the minus or the other way around basically I have no idea if the solution I provided is correct so here's the solution to both possible equations you might have meant to type instead (and if this was intentional then awesome):
1. 2x - 6x = -3 and 2. 2x + 6x = -3
Let's do 1. first!

Simplify 2x-6x to -4x

Divide each side by -4

And as you know, two negatives equal/make a positive
or

Now! Let's solve for 2.

Simplify 2x+6x to 8x

Divide both sides by 8
