Final answer:
To solve for w in the equation 7w = 91, divide both sides of the equation by 7 and simplify to get w = 13.
Step-by-step explanation:
To solve for w in the equation 7w=91, you need to isolate w on one side of the equation. This can be done by dividing both sides of the equation by 7. When you divide 91 by 7, you get w=13, which is the simplified solution to the equation.
Steps for solving the equation:
Write down the original equation: 7w = 91.
Divide both sides of the equation by 7: (7w)/7 = 91/7.
Simplify both sides: w = 13.
Check the answer by substituting 13 back into the original equation to see if it holds true: 7(13) = 91, which is correct.
