Question

aflati x:
a) x + 456=1207
b) (x-138):17=26
c){81 - [ (x-8) :4+4) - 1}:8=10​

Answer 1

a) X+ 456 = 1207

X=1207-456

x=751

b)  (x-138):17=26

x= 26 x 17

x= 442

x=442+138

x=580

c) {81 - [ (x-8) :4+4) - 1}:8=10​

x= 10 x 8

x=80

x= 80 + 82

x=162

x=162- 4

x=158

x=158x4

x=632

x= 632+8

x= 640
