-4x+2=-6;2 us this a solution to the equation

Alex17521 [72]

Hi there! Yes, x = 2 is a solution to this equation.

Let's solve this equation step by step!
$- 4x + 2 = - 6$

Subtract 2 from both sides.
$- 4x + 2 - 2 = - 6 - 2 \\ - 4x = - 8$

Now divide both sides of the equation by -4 (and remember that when dividing two negatives we end up with a positive).
$x = \frac{ - 8}{ - 4} = 2$

And therefore x = 2 is a solution to this equation.
~ Hope this helps you!
