Solve Andre's equation 2(1-3i)-2i=18

Step-by-step explanation:

2-6i-2i=18

-8i=16

i=-2

i is the variable here so you need to isolate it.

We see a number multiplied to a ( ) so let's use the distributive property first!

2*1-2*3i-2i=18

Now combine liked terms

2-8i=18

We should subtract 2 from both sides of the equation to isolate the term containing i

2-8i-2=18-2

-8i=16

Now we divide -8 from both sides to isolate i completely by itself.

-8i/-8=16/-8

i=-2

Now check our work!

2(1-3*-2)-2*-2=?=18

2(1+6)+4=?=18

14+4=18

Therefore i=-2 is correct!
