Question

4×x=216
54000:x=3
x:12000=4
x-415=326
990-x=176

Answer 1

$4 times x = 216 < = > x = frac{216}{4} = 54 \ \ 54000 div x = 3 < = > x = frac{54000}{3} = 18000 \ \ x div 12000 = 4 < = > x = 12000 times 4 = 48000 \ \ x - 415 = 326 < = > x = 326 + 415 = 741 \ \ 990 - x = 176 < = > x = 990 - 176 = 814$
