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!


2x-6x=-3

Simplify 2x-6x to -4x


-4x=-3

Divide each side by -4


x=(-3)/(-4)

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


x=(3)/(4) or
x=0.75

Now! Let's solve for 2.


2x+6x=-3

Simplify 2x+6x to 8x


8x=-3\\

Divide both sides by 8


x=(-3)/(8)


x=-(3)/(8) or
x=-0.375
