Question

Please help me on all the questions thanks !!!!!!!!!!!!!!!!!!

Answer 1

$3x-17=4\\ 3x=21\\ x=7\\\\ \frac{x}{20}-41=59\\ \frac{x}{20}=100\\ x=2000\\\\ 3(2x+7)-3x=18\\ 6x+21-3x=18\\ 3x=-3\\ x=-1\\\\ -2(5-x)+16=-14\\ -10+2x+16=-14\\ 2x=-20\\ x=-10\\\\ 2x+4\leq20\\ 2x\leq16\\ x\leq8\\\\ 21-9x\geq-6\\ -9x\geq-27\\ x\leq3\\\\ 144\geq-12x\\ x\geq-12\\\\ \frac{x}{8}$

$\frac{3}{2}x+\frac{1}{5}=\frac{3}{4}\\ 30x+4=15\\ 30x=11\\ x=\frac{11}{30}\\\\ x-\frac{2}{6}=\frac{2}{3}\\ 6x-2=4\\ 6x=6\\ x=1\\\\ -\frac{4}{5}x+6=12\\ -4x+30=60\\ -4x=30\\ x=-7.5$
