3x+6 = 2x + 4
Im detail pls

x = -2

Step-by-step explanation:

First, you need to subtract 2x from both sides. This is because you can't have the same variable (in this case, is x) on 2 different sides, you need to combine them. In this case, you're subtracting since positive (+) 2 and negative (-) 2 will cancel each other out.

3x + 6 = 2x + 4

-2x        -2x

This makes the equation:

x + 6 = 4

Now, all you need to do is subtract 6 from both sides. You're subtracting instead of adding to both sides, because positive (+) 6 and negative (-) 6 cancel each other out.

x + 6 = 4

    -6   -6

This makes the

x = -2

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
