Question

The solution of which of the following equations is neither a positive fraction nor an integer?

2x + 6 =0
3x - 5 = 0
5x - 8 = x + 4
4x + 7 = x + 2 ​

Answer 1

Answer:

$2x + 6 = 0 \\ 2x = - 6 \\ x = \frac{ - 6}{2} \\ \boxed{x = \underline{ \underline{ - 3}}} \\ \\ 3x - 5 = 0 \\ 3x = 5 \\ \boxed{x = \underline{ \underline{ \frac{5}{3} }}} \\ \\ 5x - 8 = x + 4 \\ 5x - x = 4 + 8 \\ 4x = 12 \\ x = \frac{12}{4} \\ \boxed{x = \underline{ \underline{3}}} \\ \\ 4x + 7 = x + 2 \\ 4x - x = 2 - 7 \\ 3x = - 5 \\ \boxed{ x = \underline{ \underline{ \frac{ - 5}{3} }}}$
