36-0+(7a-36)=6x7

36+(7a-36)=42

7a-36=42-36

7a-36=6

7a=6+36

7a=42

a=42:7

a=6

[(36 - 46:2x0) + (ax7-3x12)]: 7 = 6

[(36 - 23x0) + (ax7-36)]: 7 = 6

[(36 - 0) + (ax7-36)]: 7 = 6

[36 + (ax7-36)]: 7 = 6

36 + (ax7-36) = 6 x 7

36 + (ax7-36) = 42

ax7-36 = 42 - 36

ax7-36 = 6

ax7 = 6 + 36

ax7 = 42

a=42 : 7

a = 6

v: [36+ (6x7-36)]: 7 =

= [36+ (42-36)]: 7 =

= (36 + 6) : 7 =

= 42 : 7 =

= 6
