The solution of which of the following equations is neither a fraction nor an integer
(a) 2x + 6 = 0
(b) 3x - 5 = 0
(c) 5x - 8 = x + 4
(d) 4x + 7 = x + 2
Solution:
Let’s solve each of the equations to find out the correct option.
(a) 2x + 6 = 0
2x = - 6
x = -3, which is an integer
(b) 3x - 5 = 0
3x = 5
x = 5/3, which is a fraction.
(c) 5x - 8 = x + 4
4x = 12
x = 3, which is an integer
(d) 4x + 7 = x + 2
3x = -5
x = -5/3, which is neither a fraction nor an integer
Hence out of the four options, the correct option is (d) 4x + 7 = x + 2, which is neither a fraction nor an integer.
✦ Try This: The solution of which of the following equations is neither a fraction nor an integer? (a) x + 3 = 0, (b) 3x + 5 = 0, (c) 2x - 4 = x + 2, (d) 4x - 7 = x + 2
Let’s solve each of the equation to find out the correct option.
(a) x + 3 = 0
x = -3, which is an integer
(b) 3x + 5 = 0
3x = - 5
x = - 5/3, which neither a fraction nor an integer.
(c) 2x - 4 = x + 2
2x - x = 6 + 4
x = 10, which is an integer
(d) 4x - 7 = x + 2
4x - x = 2 + 7
3x = 9
x = 3, which is an integer
Hence out of the four options, the correct option is (b) 3x + 5 = 0, which is neither a fraction nor an integer.
