Question

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

Answer 1

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