Answer 1

74+13*65=x+5*(196-7*20)=37*24*5-x=37
919=x+5*56=37*24*5-x=37
x+5*56=919       888*5-x=37
x+280=919         4440-x=37
x=919-280          x=4440-37
x=639                 x=4403

74+13*65=639+5*(196-7*20)=37*24*5-4403=100-7*9

Answer 2

75+13•(86-21)=75+13•65=
75+845=920
x+5•(196-140)=920
x+5•56=920→x=920-280
x=640
100-63=37
888•5-x=37→4440-37=x
x=4403
