Question

3(x+5-2(1-3x)>4(1+x)-2
Do 1 grau

Answer 1

Resposta:

$X\geq \frac{7}{17}$

Explicação passo a passo:

$3(x+5-2(1-3x))\geq 4(1+x)-2$

$3(x+5-2+6x)\geq 4(1+x)-2$

$3(x+5-2+6x)\geq 4+4x-2$

$3(7x+5-2)\geq 4+4x-2$

$3(7x+3)\geq 4+4x-2$

$3(7x+3)\geq 2+4x$

$21x+9\geq 2+4x$

$21x+9-4x\geq 2$

$21x-4x\geq 2-9$

$17x\geq 2-9$

$17x\geq -7$

$x\geq -\frac{7}{17}$

$S=x\geq -\frac{7}{17}$

Answer 2

3(x+5) -2(1-3x)>4(1+x)-2

3x+15 - 2+6x > 4+4x - '2'

9x+14 >2+4x

9x-4x > 2 - 14

5x > - 12

X > '-12/5'
