When x equals what number, the value of X − x − 13 is equal to the value of 7 − x + 35

When x equals what number, the value of X − x − 13 is equal to the value of 7 − x + 35

According to the meaning of the title, we get x − x − 13 = 7 − x + 35, remove denominator: 15x-5 (x-1) = 105-3 (x + 3), remove bracket: 15x-5x + 5 = 105-3x-9, transfer term: 15x-5x + 3x = 105-9-5, merge: 13X = 91, coefficient into 1, get: x = 7 ∪ when x = 7, the value of X − x − 13 is equal to that of 7 − x + 35
