x-\ Kathryn's\ points\\\\
y-\ Michael's\ points\\\\
 \left \{ {{x+y=425} \atop {y+70=2x\ \ | subtract\ 70}} \right. \\\\  \left \{ {{x+y=425} \atop {y=2x-70}} \right. \\ substitution\ method\\\\
x+2x-70=425\\\\
3x-70=425\ \ | add\ 70\\\\
3x=495\ \ \ | divide\ by\ 3\\\\
x=165\\\\
y=2x-70=2*165-70=330-70=260\\\\
Kathryn\ scored\ 165\ points\ and\ Michael\ 260

Im having a hard time on this question and I hope you can help.

The answer would be x ≠ 0

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First start with the left side, doing distributive property

So... -2(x) = -2x and -2(5) = -10 Therefore on the left side you now have -2x -10

Next do the same on the right side

-2(x) = - 2x and -2(-2) = 4 so you have -2x + 4 + 5 and you add 4 and 5, leaving you with -2x + 9

Now that you have simplified both sides the problem now looks like this:

-2x - 10 = -2x + 9

Because you have equal terms on both sides (-2) those cancel out so you have -10 = 9

Just from looking at this we know that the statement is false because -1o does not equal 9

*The symbol, "≠" means not equal to"
