Question

6.Resolva, em R, a inequação

4x - 1 + 2(1 - 3x)≤ 0​

Answer 1

Resposta:

$x\leq \frac{1}{2}$

Explicação passo a passo:

$4x-1+2( 1-3x)\leq 0\\\\4x-1+2(1-3x)\geq 0+1\\\\4x+2(1-3x)\geq 1\\\\-2x+2\geq 1\\\\-2x+2-2\geq 0\\\\-2x+2\geq 1-2\\\\-2x+2\geq -1\\\\(-2x)(-1)\leq (-1)(-1)\\\\2x\leq 1\\\\x\leq 1:2\\\\x\leq \frac{1}{2}$
