25 points? Suri's age is 4 less than 3 times her cousin's age. Suri is 17 years old. Which method can be used to find c, her cousin's age?

1. Subtract 4 from 17, then divide by 3.
2. Solve the equation 4c - 3 = 17.
3. Add 4 to 17, then multiply by 3.
4. Solve the equation 3c - 4 = 17.

1, 2, 3, or 4? Thanks :)

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
