Answer:
X=3
Step-by-step explanation:
Step 1: Find the square root of 64
since there is an exponent of 2 around your paranthesis, you must get rid of that first, by finding the square root of the first part of the equation and 64. then you will have (2x+2)=8
Step 2: Subtract 2
next subtract 2 from both sides of the equation, and you will have 2x=6
Step 3: divide by 2
lastly, divide each side by 2. you will get x=3
