7x + 3 = 9x - 7
Subtract 7x from each side: + 3 = 2x - 7
Add 7 to each side: 10 = 2x
Divide each side by 2 : ***5 = x ***
The solution to the equation 7 x + 3 = 9 x − 7 is x = 5 . This was achieved by isolating the variable through subtraction and division. Verifying the solution shows that both sides of the equation are equal when x = 5 .
