How many solutions does the equation have?
Alexxx [7]
-6 + 6 = 0 0 + -2x = 12 + 6 -2x = 12 + 6<span>4x+2(x-3)=8x+12  is our main problem right? so...
</span><span>4x + (-3 * 2 + x * 2) = 8x + 12
4x + (-6 + 2x) = 8x + 12
</span><span>So next we do: 
</span><span>-6 + 4x + 2x = 8x + 12
Reorder the terms :)    </span><span>-6 + 6x = 12 + 8x
</span>Now were going to solve for x
<span>-6 + -2x = 12 + 8x + -8x
</span><span>8x + -8x = 0
-6 + -2x = 12 + 0
-6 + -2x = 12
</span>-6 + 6 = 0
0 + -2x = 12 + 6
-2x = 12 + 6=
<span>-2x = 18
so now were just going to divide each side by -2
and so thats going to be like this
-2x = 18</span>
/ -2     /-2
0        -9
so whats left over is x = -9
So your answer is A.
