Answer:
4
Explanation:
(is the equation below x - 7 or x +7, I am working with x + 7)
9+ (2x - 6) is equivalent to x + 7
9 + (2x - 6) = x + 7
Open the bracket
9 + 2x - 6 = x + 7
2x + 3 = x +7
Subract 3 from both sides
2x = x + 4
Subtact x from both sides
X = 4
Confirm if the equation in the question is x +7 or x - 7
