Question

Alguien me podría ayudar a hacer esto?$(2x-5)(1-x)=(4-2x)(x-\frac{1}{2})$

Answer 1

$(2x - 5) \times (1 - x) = (4 - 2x) \times (x - \frac{1}{2} ) = \\ \\ 2x - 2 {}^{2} - 5 + 5x = 4x - 2 - 2x {}^{2} + x = \\ \\ 2x - 5 + 5x = 4x - 2 + x = \\ \\ 7x - 5 = 5x - 2 = \\ \\ 7x - 5x = - 2 + 5 = \\ \\ 2x = 3 = \\ \\ 2x \div 2 = 3 \div 2 = \\ \\ x = 3 \div 2 = \\ \\ x = \frac{3}{2}$
