Answer:
x = the unknown number = 26
Step-by-step explanation:
Let
x = the unknown number
i multiply by 14 qand add 12
(x * 14) + 12
= 14x + 12
i get the same answer if i multiply by 5 and add 246
(x * 5) + 246
= 5x + 246
Equate both equations
14x + 12 = 5x + 246
14x - 5x = 246 - 12
9x = 234
x = 234 / 9
x = 26
x = the unknown number = 26
