Hey there Alex,
With a problem like that, you have to get the variable (in this case it is W) by itself.
Now W is being divided by 4-13 which is -9, so it ends up looking like this.
In order to get W by itself, you need to multiply out the denominator.
That means take the denominator and multiply both sides by it.
The -9's cancel out and you are left with W = (11 x -9) which is -99.
W = -99
There is one solution.
Just divide the 2nd line by two to get -2x + y= 3, then put it in slope-intercept to get y= -2x + 3
THen
y=2x+3
y= -2x + 3 subtract
4x=0
so x=0
plug in 0 for x
y= 2(0) +3
so y =3.
plug in to check
3=0+3 checkmark
-4(0) +2(3) = 6 checkmark
