Answer
The solution is -2
Work Step by Step
10w+8=w-10 Subtract 8 from both sides
10w+8-8=w-10 -8
10w =w-18 Subtract w from both sides
10w-w =w-18-w
9w =-18 Divide by 9 on both sides
$\frac{9w}{9}$=$\frac{-18}{9}$
w=-2
The solution is -2
Check
10w+8=w-10 Replace x with -2
10(-2)+8=-2-10 Multiply
-20+8=-12
-12=-12
