45 + 11i

To do problems like these, treat them as you would multiplying two binomials. Just FOIL them, and keep in mind that (i)^2 is equal to -1.

8-2x=-8x+14<br><br><br> answer choices <br> x=-1<br> x=-3/5<br> x=3/5<br> x=1
navik [9.2K]
Hello there!

8 - 2x = -8x + 14

Let's start by subtracting 8 to both sides

8 - 2x - 8 = -8x + 14 - 8

-2x = -8x + 6

Let's add 8x to both sides

-2x + 8x = -8x + 6 +8x

6x = 6

Divide both sides by 6

6x/6 = 6/6

x = 1

The correct answer is option D

I hope this helps!
