Oi tudo bem?
Explicação passo a passo:
a- 2x >0+6
2x>6 ( subtrai 0)
X= >6/2
X > 3
b- 4X+3-5x <2
4x-5x < -2-3
X < -5 (-1)
X= >5
-[tex]c-\left \{ {{2x-8\geq 0} \atop {3-x\geq 0}} \right. \\\\\left \{ {{2x-8\leq 0} \atop {3-x \leq 0}} \right.[/tex]
[tex]\left \{ {{X\geq 4} \atop {X \leq 3}} \right. \\\\\left \{ {{X\leq 4} \atop {X\geq 3}} \right. \\\\X= (3,4)[/tex]
[tex]d-\left \{ {{3x-6\leq 0} \atop {5-x>0}} \right. \\\\\left \{ {{3x-6\geq 0} \atop {5-x< 0}} \right. \\ \\\left \{ {{x\leq 2} \atop {x<5}} \right. \\\\\left \{ {{x\geq 2} \atop {x>5}} \right. \\\\\left \{ {{X= 2} \atop {X= 5}} \right.[/tex]
Bons Estudos !!
