Question

2.(6x - 4) = 3.(4x - 1)

Answer 1

Resposta:

$2x(6x - 4) = 3x(4x - 1)\\\\2x\left(6x-4\right)\\\\=2x\cdot \:6x-2x\cdot \:4\\\\=2\cdot \:6xx-2\cdot \:4x\\\\2\cdot \:6xx-2\cdot \:4x\\\\3x\left(4x-1\right)\\\\=3x\cdot \:4x-3x\cdot \:1\\\\3\cdot \:4xx-3\cdot \:1\cdot \:x\\\\\\=12x^2-3x\\\\12x^2-8x=12x^2-3x\\\\12x^2-8x-\left(12x^2-3x\right)=12x^2-3x-\left(12x^2-3x\right)\\\\-5x=0\\\\\frac{-5x}{-5}=\frac{0}{-5}\\\\x=0$
