Question

examine whether half is a solution of the equation 2x + 1 by 2 is equal to 4 x minus one by two

Answer 1

Step-by-step explanation:

$\frac{2x + 1}{2} = \frac{4x - 1}{2} \\ = 2(2x + 1) = 2(4x - 1) \: \: \: (using \: cross \: multiplication) \\ 4x + 2 = 8x - 2 \\ 4x - 8x = - 2 - 2 \\ - 4x = - 4 \\ x = \frac{ - 4}{ - 4} = 1 \\ x = 1$

no solution is 1
