divide by -10
y=-1

sub back

-2x-y=9
-2x-(-1)=9
-2x+1=9
-2x=8
divide by -2
x=-4

y=-1

Solve for w. <br><br> 1/3w + 5/6w - 2 = -w

Scorpion4ik [409]

Answer: $w=\frac{12}{13}$

Step-by-step explanation:

To solve for w, we want to isolate the variable.

$\frac{1}{3}w +\frac{5}{6}w-2=-w$ [add both sides by 2 and w]

$\frac{1}{3}w +\frac{5}{6}w+w=2$ [convert to same denominator]

$\frac{2}{6}w +\frac{5}{6}w+\frac{6}{6} w=2$ [add]

$\frac{13}{6} w=2$ [multiply both sides by 6/13]

$w=\frac{12}{13}$

Now we know that $w=\frac{12}{13}$ .
