Answer» (i) x+8=9=>x=9-8=1(ii)x+36=-40=>x=-40-36=-(40+36)=-76(iii)x-9=5=>x=5+9=14(iv)x/2=3=>x=3*2=6(v)-9x=21=>x=-21/9=-7/3(vi)2(7+x)=9x=>14+2x=9x=>14=9x-2x=7x=>x=14/7=2(vii)3x+8=-1=>3x=-1-8=-9=>x=-3(viii) question not clear.(ix) (x/3)-2=0=>x/3=2=>x=6(x)(4/5)x+x=18/5=>9x/5=18/5=>x=(18/5)*(5/9)= 2(xi)1-1x/7=-8=>1+8=x/7=>9*7=x=>x=63 |
