9 140 - Х ) * 3 + 55 = 172
First, let's simplify the equation:
(9 140 - Х) 3 + 55 = 172(1260 - Х) 3 + 55 = 1723780 - 3Х + 55 = 1723780 - 3Х + 55 - 3780 = 172 - 3780-3Х + 55 = -3608
Next, let's isolate the variable:
-3Х = -3663Х = -3663 / -3Х = 1221
Therefore, the value of Х is 1221.
9 140 - Х ) * 3 + 55 = 172
First, let's simplify the equation:
(9 140 - Х) 3 + 55 = 172
(1260 - Х) 3 + 55 = 172
3780 - 3Х + 55 = 172
3780 - 3Х + 55 - 3780 = 172 - 3780
-3Х + 55 = -3608
Next, let's isolate the variable:
-3Х = -3663
Х = -3663 / -3
Х = 1221
Therefore, the value of Х is 1221.
