Answer 1

$1)left { {frac{6x^{2}+11x-3 }{2}*2geq(3x^{2}-5)*2} atop {7x+2>11x-3}} right.\\left { {{6x^{2}+11x-3geq 6x^{2}-10 } atop {-4x>-5}} right.\\left { {{11xgeq-7 } atop {x<1,25}} right.\\left { {{xgeq-frac{7}{11}} atop {x<1,25}} right. \\xin[-frac{7}{11},1,25)$

$2)left { {{frac{11x-3}{3}*15geqfrac{7x+1}{5}*15} atop {7x+2geq11x-3 }} right.\\left { {{55x-15geq 21x+3} atop {-4xgeq-5 }} right.\\left { {{34xgeq18 } atop {xleq1,25 }} right.\\left { {{xgeqfrac{9}{17}  } atop {xleq1,25 }} right.\\xin[frac{9}{17};1,25]$
