Answer:
w=-100
Step-by-step explanation:
We are given the equation:
166= -w +66
To solve for x, we must get x by itself on one side of the equation.
66 is being added to -w. The inverse of addition is subtraction. Subtract 66 from both sides of the equation.
166-66= -w+66-66
166-66= -w
100= -w
-1 and w are being multiplied. The invers of multiplication is division. Divide both sides of the equation by -1.
100/-1= -w/-1
100/-1=w
-100=w
Let's check our solution. Plug -100 in for w.
166= -w+66
166= -(-100)+66
166=100+66
166=166
The statement above is true, so we know our solution is correct.
The solution to 166= -w+66 is w= -100
