Question

2015 . ( 3x - 2016 ) = 0

231 - ( x - 6 ) = 1339 : 13

207 - 63 . 9 + 100 =?

Answer 1

a)

2015.(3x -2016)= 0

=> 3x - 2016 =0

=> 3x = 2016

=> x = 2016:3

x =  672

 

Answer 2

2015.(3x-2016)=0

=> 3x-2016=0

=> 3x=2016

=> x=2016:3

=> x=672

231-(x-6)=1339:13

=> 231-x+6=103

=> 237-x=103

=> x=237-103

=> x=134

207-63.9+100

= 207-567+100

= 207-(567-100)

= 207-467

= -260
