9 ( x − 5 ) = 4 x − 5 9 ⋅ x + 9 ⋅ ( − 5 ) = 4 x − 5 9 x − 45 = 4 x − 5 / + 45 9 x − 45 + 45 = 4 x − 5 + 45 9 x = 4 x + 40 / − 4 x 9 x − 4 x = 4 x − 4 x + 40 5 x = 40 / : 5 5 x : 5 = 40 : 5 x = 8
The solution to the equation 9 ( x − 5 ) = 4 x − 5 is x = 8 . To arrive at this, we distributed, combined terms, and isolated x . Finally, we divided to find the value of x .
