Step-by-step explanation:

Step 1: Define

Identify

3(x + 4) - 1 = 7

Step 2: Solve for x

[Addition Property of Equality] Add 1 on both sides:                                     3(x + 4) = 8[Division Property of Equality] Divide 3 on both sides:                                 x + 4 = 8/3[Subtraction Property of Equality] Subtract 4 on both sides:                        x = -4/3

Welp life just is hard

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.
