Question

{5(x-2)-x>2
{1-3(x-1)<-1

Answer 1

$\left \{ {{5(x-2)-x > 2} \atop {1-3(x-1) < -1}} \right.$

$\left \{ {{5x -10-x > 2} \atop {1-3x+3 < -1}} \right.$

$\left \{4x > 2+10} \atop {-3x < -1-1-3}} \right.$

$\left \{ {{x > \frac{12}{4} } \atop {x > \frac{-5}{-3} }} \right.$

$\left \{ {{x > 3} \atop {x > 1\frac{2}{3} }} \right.$
