Answer:
A=the outcome is odd, B=the outcome is even
Is mutually exclusive because you can't have a number that is even and odd at the same time.
Hope this helps :)
-x = 2 - 3x + 6
Add 3x to both sides.
-x + 3x = 2 + 6
Simplify.
2x = 8
Divide both sides by 2.
x = 4

<span>The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.</span>
