the answer is letter (D 7) try it and it was correct.

The solution of the equation 9x=7 (x+2) is:

Option D) 7

Step-by-step explanation:

9x=7 (x+2)

Eliminating the parentheses applying distributive property:

9x=7 (x) + 7 (2)

Multiplying:

9x=7x+14

Grouping the x's on the left side of the equation: Subtracting 7x both sides of the equation:

9x-7x=7x+14-7x

Subtracting:

2x=14

Solving for x: Dividing both sides of the equation by 2:

2x/2=14/2

Dividing:

x=7

Solution: x=7 (option D)
