PLEASE HELP ME WITH THIS
Please put an easy explanation for me to understand how to do this on my own.
Answer:
Step 1: Simplify both sides of the equation.
2w=1/4
Step 2: Divide both sides by 2.
2w/2=1/4/2
Answer:
w=1/8
Answer:
So what you have to do is that first, you simplify both sides of the equation.
(2w = 1/4). Then you divide both sides by 2, (2w / 2 = 1/4 / 2). So after you do that, your left with w = 1/8. So W is equal to 1/8.
