The equation which cannot be solved in integers is ______.
विकल्प
5y – 3 = –18
3x – 9 = 0
3z + 8 = 3 + z
9y + 8 = 4y –7
उत्तर
The equation which cannot be solved in integers is 3z + 8 = 3 + z.
Explanation:
Consider the equation 3z + 8 = 3 + z
Transpose 8 to right-hand side then it becomes –8 and z to left-hand side then it becomes –z.
3z – z = 3 – 8
2z = –5
z = `-5/2`
