Question

[102+(28-2.x)]:20-5=1

Answer 1

[102+(28-2.x)]:20-5=1

[102+(28-2.x)]:20=1+5

[102+(28-2.x)]:20=6

[102+(28-2.x)]=6.20

102+(28-2.x)=120

(28-2.x)=120-102

28-2.x=18

2.x=28-18

2.x=10

x=10:2

x=5

Answer 2

[102 + (28 - 2.x)]:20 = 1=5 =6

[102 + (28-2.x)]=6. 20 = 120

(28 - 2 . x) = 120 + 102 = 222

2.x = 28 - 222 = -194

x= -194 : 2 = -97
