Question

x - 32 + x - 20 + x - 50 = 156

Answer 1

x-32+x-20+x-50=156

<=>(x+x+x)-(32+20+50)=156

<=>3*x-102=156

=>3*x=156+102

=>3*x=258

=>x=258:3

=>x=86

Answer 2

x - 32 + x - 20 + x - 50 = 156

3x - ( 32 + 20 + 50 ) = 156

3x - 102 = 156

3x = 156 + 102

3x = 258

x = 258 : 3

x = 86

Answer 3

x=86 nhé nha bạn
