Apply the distributive property to the right side of the equation as shown on the board

Evaluate the constant terms on the right side as shown on the board

Subtract 3 from both sides as shown on the board

Cancelling out +3 and -3 from both sides, we get the equation as shown on the board

Subtract 6x from both sides as shown on the board

Cancelling out 6x and -6x from the right side we get the equation as shown on the board

Subtracting 6x from 7x on the left side we get the final value of x as shown on the board

Final answer
