Apply the distributive property to the right side of the equation as shown on the board
a(bc)=a×ba×c
7x+3=6(x1)+9
7x+3=(6)(x)(6)(1)+9
7x+3=6x6+9
Evaluate the constant terms on the right side as shown on the board
7x+3=6x+3
Subtract 3 from both sides as shown on the board
7x+33=6x+33
Cancelling out +3 and -3 from both sides, we get the equation as shown on the board
7x=6x
Subtract 6x from both sides as shown on the board
7x6x=6x6x
Cancelling out 6x and -6x from the right side we get the equation as shown on the board
7x6x=0
Subtracting 6x from 7x on the left side we get the final value of x as shown on the board
x=0
Final answer
x=0
