I need the answers please.

1 Use the computer to solve the two problems that opened this chapter. (a) This is the Statics problem. 40h+15c25c=100=50+50h (b) This is the Chemistry problem. 7h8h+1i1i3i=7j=5j+2k=3j=6j+1k 2 Use the computer to solve these systems from the first subsection, or conclude 'many solutions' or 'no solutions'. (a) 2x+2y=5 (b) x+y=1 (c) x3y+z=1 (d) xy=1 x4y=0 x+y=2 x+y+2z=14 3x3y=2 (e) 4y+z=20 (f) 2x+z+w=5 2x2y+z=0yw=1x+z=53xzw=0x+yz=104x+y+2z+w=9 3 Use the computer to solve these systems from the second subsection. (a) 3x+6y=18 (b) x+y=1 (c) x1+x3=4 x+2y=6 xy=1 x1x2+2x3=5 4x1x2+5x3=17 (d) 2a+bc=2 (e) x+2yz=3 (f) x+z+w=4 2a+c=3 2x+y2x+yw=2 ab=0 xy+z+w=13x+y+z=7 4 What does the computer give for the solution of the general 22 system? ax+cy=pbx+dy=
